Shavuot in the Bible: A Critical Perspective
(טז) וְחַ֤ג הַקָּצִיר֙ בִּכּוּרֵ֣י מַעֲשֶׂ֔יךָ אֲשֶׁ֥ר תִּזְרַ֖ע בַּשָּׂדֶ֑ה וְחַ֤ג הָֽאָסִף֙ בְּצֵ֣את הַשָּׁנָ֔ה בְּאָסְפְּךָ֥ אֶֽת־מַעֲשֶׂ֖יךָ מִן־הַשָּׂדֶֽה׃
(16) and the Feast of the Harvest, of the first fruits of your work, of what you sow in the field; and the Feast of Ingathering at the end of the year, when you gather in the results of your work from the field.
  • Many scholars believe that the "Covenant Code" (Exodus 21-23) is the oldest collection of laws in the Torah.
  • No date. Indeed, it seems very likely that these festivals would be either personal or local, celebrated whenever one completes the spring harvest.
  • Based on the fact that Hag Ha'asif is at the end of the year, this must be at the beginning of the year, following Hag Hamatzot, mentioned in the previous verse.
  • The festival is called a חג which means a pilgrimage festival. Thus people must be going to some Temple/or place of worship. However, Exodus never discusses the centralization of worship. Thus a חג in Exodus would mean to a local sanctuary, not Jerusalem.

The Gezer calendar is a small inscribed limestone tablet discovered in 1908 by Irish archaeologist R. A. Stewart Macalister in the ancient Canaanite city of Gezer, 20 miles west of Jerusalem. It is commonly dated to the 10th century BCE, although the excavation was unstratified and its identification during the excavations was not in a "secure archaeological context", presenting uncertainty around the dating.

Scholars are divided as to whether the language is Phoenician or Hebrew and whether the script is Phoenician (or Proto-Canaanite) or paleo-Hebrew.

(כב) וְחַ֤ג שָׁבֻעֹת֙ תַּעֲשֶׂ֣ה לְךָ֔ בִּכּוּרֵ֖י קְצִ֣יר חִטִּ֑ים וְחַג֙ הָֽאָסִ֔יף תְּקוּפַ֖ת הַשָּׁנָֽה׃
(22) You shall observe the Feast of Weeks, of the first fruits of the wheat harvest; and the Feast of Ingathering at the turn of the year.
  • This is a difficult text--what does "Weeks" mean? Exodus gives us no answer and thus can only be interpreted based on other texts.
  • Biblical scholars believe that the word "Weeks" is an interpolation/emendation by the Deuteronomist,, who changed the original "חג הקציר" with חג השבועות.
  • Here "wheat" is mentioned, not barley. Wheat is a later harvest than barley, and thus, if we identify this with the other harvest holidays elsewhere in the Torah, this is the latter one. According to many scholars, Matzot is the barley harvest festival.

(9) The LORD spoke to Moses, saying: (10) Speak to the Israelite people and say to them: When you enter the land that I am giving to you and you reap its harvest, you shall bring the first sheaf of your harvest to the priest. (11) He shall elevate the sheaf before the LORD for acceptance in your behalf; the priest shall elevate it on the day after the sabbath. (12) On the day that you elevate the sheaf, you shall offer as a burnt offering to the LORD a lamb of the first year without blemish. (13) The meal offering with it shall be two-tenths of a measure of choice flour with oil mixed in, an offering by fire of pleasing odor to the LORD; and the libation with it shall be of wine, a quarter of a hin. (14) Until that very day, until you have brought the offering of your God, you shall eat no bread or parched grain or fresh ears; it is a law for all time throughout the ages in all your settlements. (15) And from the day on which you bring the sheaf of elevation offering—the day after the sabbath—you shall count off seven weeks. They must be complete: (16) you must count until the day after the seventh week—fifty days; then you shall bring an offering of new grain to the LORD. (17) You shall bring from your settlements two loaves of bread as an elevation offering; each shall be made of two-tenths of a measure of choice flour, baked after leavening, as first fruits to the LORD. (18) With the bread you shall present, as burnt offerings to the LORD, seven yearling lambs without blemish, one bull of the herd, and two rams, with their meal offerings and libations, an offering by fire of pleasing odor to the LORD. (19) You shall also offer one he-goat as a sin offering and two yearling lambs as a sacrifice of well-being. (20) The priest shall elevate these—the two lambs—together with the bread of first fruits as an elevation offering before the LORD; they shall be holy to the LORD, for the priest. (21) On that same day you shall hold a celebration; it shall be a sacred occasion for you; you shall not work at your occupations. This is a law for all time in all your settlements, throughout the ages.
  • Scholars attribute this section of Leviticus to the Holiness Code, a source from a different priestly author than the composer of the first 18 chapters of Leviticus.
  • This is by far the most complicated, detailed description of these holidays. We will now look at this again, verse by verse.
(ט) וַיְדַבֵּ֥ר יְהוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃
(9) The LORD spoke to Moses, saying:

The fact that there is a new header demonstrates that this is a new holiday. Distinct from Hag Hamatzot that preceded it.

(י) דַּבֵּ֞ר אֶל־בְּנֵ֤י יִשְׂרָאֵל֙ וְאָמַרְתָּ֣ אֲלֵהֶ֔ם כִּֽי־תָבֹ֣אוּ אֶל־הָאָ֗רֶץ אֲשֶׁ֤ר אֲנִי֙ נֹתֵ֣ן לָכֶ֔ם וּקְצַרְתֶּ֖ם אֶת־קְצִירָ֑הּ וַהֲבֵאתֶ֥ם אֶת־עֹ֛מֶר רֵאשִׁ֥ית קְצִירְכֶ֖ם אֶל־הַכֹּהֵֽן׃

(10) Speak to the Israelite people and say to them: When you enter the land that I am giving to you and you reap its harvest, you shall bring the first sheaf of your harvest to the priest.

According to its simple meaning, this verse commands the Israelite to bring the first of his harvest to the priest. The verb וקצרתם means that this is a grain harvest, and since the wheat harvest is referred to later, this must be the barley harvest, which precedes that of the grain.

(יא) וְהֵנִ֧יף אֶת־הָעֹ֛מֶר לִפְנֵ֥י יְהוָ֖ה לִֽרְצֹנְכֶ֑ם מִֽמָּחֳרַת֙ הַשַּׁבָּ֔ת יְנִיפֶ֖נּוּ הַכֹּהֵֽן׃
(11) He shall elevate the sheaf before the LORD for acceptance in your behalf; the priest shall elevate it on the day after the sabbath.

The priest elevates the sheaf as is often done with sacrifices.

The problematic words here (and later in the passage) are “after the Sabbath.” The problem goes deeper than trying to identify which Sabbath the verse is talking about (a HUGE dispute among ancient Jews). The problem is that there is no date to the holiday, and indeed, were it not for this phrase (and its other appearances) the date on which this offering is brought would seem to be completely personal. “After the Sabbath” implies that there is a specific date in which this offering must be brought to the priest.

This leads Milgram (Leviticus, p. 2060) to suggest that the addition of the phrase would “allow the farmers in a particular area, devotees of the same regional sanctuary, to begin the grain harvest during the same week and, collectively, celebrate the firstfruits festival together on the same day.” It seems that Milgram thinks that originally the phrase “after the Sabbath” did not have any particular Sabbath in mind. He describes the gloss as “a vestige of the first attempt to prescribe a pilgrimage festival for the firstfruit of the grain heretofore brought by individual farmers whenever their grain ripened.” He calls the author the "Sunday Pentacostalist."

Again, it is worth remembering that Leviticus also does not mention the centralization of worship. Only Deuteronomy does. Thus there is no reason to suppose that this holiday was celebrated on the same day in every location.

Another interesting suggestion as to how to interpret the word is that ממחרת השבת does not refer to the seventh day of the week, but to an older meaning of the word "shabbat"--the middle day of the month. This mostly emerges from the pairing of "Hodesh" with "Shabbat" as in II Kings 4:23, וַיֹּ֗אמֶר מַ֠דּוּעַ אתי [אַ֣תְּ] הלכתי [הֹלֶ֤כֶת] אֵלָיו֙ הַיּ֔וֹם לֹֽא־חֹ֖דֶשׁ וְלֹ֣א שַׁבָּ֑ת וַתֹּ֖אמֶר שָׁלֽוֹם׃" or Isaiah 1:13, "לֹ֣א תוֹסִ֗יפוּ הָבִיא֙ מִנְחַת־שָׁ֔וְא קְטֹ֧רֶת תּוֹעֵבָ֛ה הִ֖יא לִ֑י חֹ֤דֶשׁ וְשַׁבָּת֙ קְרֹ֣א מִקְרָ֔א לֹא־אוּכַ֥ל אָ֖וֶן וַעֲצָרָֽה׃." If this is the meaning, then counting would begin on the 16th of the month, as it does in later Pharisaic tradition.

(יד) וְלֶחֶם֩ וְקָלִ֨י וְכַרְמֶ֜ל לֹ֣א תֹֽאכְל֗וּ עַד־עֶ֙צֶם֙ הַיּ֣וֹם הַזֶּ֔ה עַ֚ד הֲבִ֣יאֲכֶ֔ם אֶת־קָרְבַּ֖ן אֱלֹהֵיכֶ֑ם חֻקַּ֤ת עוֹלָם֙ לְדֹרֹ֣תֵיכֶ֔ם בְּכֹ֖ל מֹשְׁבֹֽתֵיכֶֽם׃ (ס)
(14) Until that very day, until you have brought the offering of your God, you shall eat no bread or parched grain or fresh ears; it is a law for all time throughout the ages in all your settlements.

Once the first grain has been offered, along with the attendant sacrifices, the new grain harvest may be eaten. Many scholars have pointed out that in different regions in Israel the grain will ripen at different times. Thus it does not really make sense to have one unified time for all of Israel in which new grain could be eaten. This is what leads many to conclude that the holiday was originally personal or at least regional.

(יב) וַעֲשִׂיתֶ֕ם בְּי֥וֹם הֲנִֽיפְכֶ֖ם אֶת־הָעֹ֑מֶר כֶּ֣בֶשׂ תָּמִ֧ים בֶּן־שְׁנָת֛וֹ לְעֹלָ֖ה לַיהוָֽה׃ (יג) וּמִנְחָתוֹ֩ שְׁנֵ֨י עֶשְׂרֹנִ֜ים סֹ֣לֶת בְּלוּלָ֥ה בַשֶּׁ֛מֶן אִשֶּׁ֥ה לַיהוָ֖ה רֵ֣יחַ נִיחֹ֑חַ וְנִסְכֹּ֥ה יַ֖יִן רְבִיעִ֥ת הַהִֽין׃
(12) On the day that you elevate the sheaf, you shall offer as a burnt offering to the LORD a lamb of the first year without blemish. (13) The meal offering with it shall be two-tenths of a measure of choice flour with oil mixed in, an offering by fire of pleasing odor to the LORD; and the libation with it shall be of wine, a quarter of a hin.

Modern scholars disagree over whether these verses are a later interpolation, reflecting the centralization of worship, or whether they are part of the original strata and that the individual farmer was meant to bring these sacrifices, along with the first omer.

(טו) וּסְפַרְתֶּ֤ם לָכֶם֙ מִמָּחֳרַ֣ת הַשַּׁבָּ֔ת מִיּוֹם֙ הֲבִ֣יאֲכֶ֔ם אֶת־עֹ֖מֶר הַתְּנוּפָ֑ה שֶׁ֥בַע שַׁבָּת֖וֹת תְּמִימֹ֥ת תִּהְיֶֽינָה׃ (טז) עַ֣ד מִֽמָּחֳרַ֤ת הַשַּׁבָּת֙ הַשְּׁבִיעִ֔ת תִּסְפְּר֖וּ חֲמִשִּׁ֣ים י֑וֹם וְהִקְרַבְתֶּ֛ם מִנְחָ֥ה חֲדָשָׁ֖ה לַיהוָֽה׃
(15) And from the day on which you bring the sheaf of elevation offering—the day after the sabbath—you shall count off seven weeks. They must be complete: (16) you must count until the day after the seventh week—fifty days; then you shall bring an offering of new grain to the LORD.

Now that we have clarified that “after the Sabbath” refers to an attempt to unify a personal holiday into a regional one, the counting make more sense. The count begins the day that the first omer of barley is brought, and continues until the wheat harvest, when another offering of new grain is brought. Again, this counting is either personal or regional. Leviticus has no notion of centralization of worship.

(יז) מִמּוֹשְׁבֹ֨תֵיכֶ֜ם תָּבִ֣יאּוּ ׀ לֶ֣חֶם תְּנוּפָ֗ה שְׁ֚תַּיִם שְׁנֵ֣י עֶשְׂרֹנִ֔ים סֹ֣לֶת תִּהְיֶ֔ינָה חָמֵ֖ץ תֵּאָפֶ֑ינָה בִּכּוּרִ֖ים לַֽיהוָֽה׃ (יח) וְהִקְרַבְתֶּ֣ם עַל־הַלֶּ֗חֶם שִׁבְעַ֨ת כְּבָשִׂ֤ים תְּמִימִם֙ בְּנֵ֣י שָׁנָ֔ה וּפַ֧ר בֶּן־בָּקָ֛ר אֶחָ֖ד וְאֵילִ֣ם שְׁנָ֑יִם יִהְי֤וּ עֹלָה֙ לַֽיהוָ֔ה וּמִנְחָתָם֙ וְנִסְכֵּיהֶ֔ם אִשֵּׁ֥ה רֵֽיחַ־נִיחֹ֖חַ לַיהוָֽה׃ (יט) וַעֲשִׂיתֶ֛ם שְׂעִיר־עִזִּ֥ים אֶחָ֖ד לְחַטָּ֑את וּשְׁנֵ֧י כְבָשִׂ֛ים בְּנֵ֥י שָׁנָ֖ה לְזֶ֥בַח שְׁלָמִֽים׃
(17) You shall bring from your settlements two loaves of bread as an elevation offering; each shall be made of two-tenths of a measure of choice flour, baked after leavening, as first fruits to the LORD. (18) With the bread you shall present, as burnt offerings to the LORD, seven yearling lambs without blemish, one bull of the herd, and two rams, with their meal offerings and libations, an offering by fire of pleasing odor to the LORD. (19) You shall also offer one he-goat as a sin offering and two yearling lambs as a sacrifice of well-being.

Verse 17 is posited to be part of the original strata.

Verses 18-19 are later additions by the editor of H, who converts an individual offering into a public offering in the sanctuary.

(כ) וְהֵנִ֣יף הַכֹּהֵ֣ן ׀ אֹתָ֡ם עַל֩ לֶ֨חֶם הַבִּכּוּרִ֤ים תְּנוּפָה֙ לִפְנֵ֣י יְהוָ֔ה עַל־שְׁנֵ֖י כְּבָשִׂ֑ים קֹ֛דֶשׁ יִהְי֥וּ לַיהוָ֖ה לַכֹּהֵֽן׃
(20) The priest shall elevate these—the two lambs—together with the bread of first fruits as an elevation offering before the LORD; they shall be holy to the LORD, for the priest.

Note the use of the word "bikkurim" "first fruits". This is the same word used in Exodus 23 and 34. However, it is unclear if the date of this holiday is the same as that in Exodus. Exodus has only one festival and Leviticus has two. Furthermore, here instead of ears of corn being offered, bread is being offered, making it more likely that this is a latter festival, at the end of the harvest, the same one referred to in Exodus.

(כא) וּקְרָאתֶ֞ם בְּעֶ֣צֶם ׀ הַיּ֣וֹם הַזֶּ֗ה מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֣א תַעֲשׂ֑וּ חֻקַּ֥ת עוֹלָ֛ם בְּכָל־מוֹשְׁבֹ֥תֵיכֶ֖ם לְדֹרֹֽתֵיכֶֽם׃
(21) On that same day you shall hold a celebration; it shall be a sacred occasion for you; you shall not work at your occupations. This is a law for all time in all your settlements, throughout the ages.

This is not a pilgrimage festival, as can be seen from the words “in all your settlements,” and from the fact that the word “חג” is not used anywhere in connection with the day. The offerings listed above are brought to the sanctuary (be it central or local) but the work prohibition applies everywhere.

To conclude, the source that lies behind the Holiness Code describes two independent first fruits festivals. The first was for the barley and the second for wheat. These offerings are not part of pilgrimage festivals. They are occasions in which farmers had to bring firstfruits and sacrifices to their local sanctuaries. The redactors of the Holiness code attempt to regionalize these occasions by dictating that they both occur on the day after the Sabbath, and that they are separated by seven “Sabbath-weeks.” The redactors of H add in offerings brought to a central sanctuary but fall short of calling this a חג a pilgrimage festival.

However, as elsewhere in the Bible there is no date for these offerings nor is there any connection to Hag Hamatzot. "After the Sabbath" did not originally refer to the Sabbath after Matzot (as the Sadducees/Dead Sea Sect posited) nor to the Sabbath after the first day of Matzot (Pharisees/Rabbis). The seven weeks did not connect Pesah with Shavuot. They connect a dateless barley harvest with a dateless wheat harvest.

(יד) וְאִם־תַּקְרִ֛יב מִנְחַ֥ת בִּכּוּרִ֖ים לַיהוָ֑ה אָבִ֞יב קָל֤וּי בָּאֵשׁ֙ גֶּ֣רֶשׂ כַּרְמֶ֔ל תַּקְרִ֕יב אֵ֖ת מִנְחַ֥ת בִּכּוּרֶֽיךָ׃
(14) If you bring a meal offering of first fruits to the LORD, you shall bring new ears parched with fire, grits of the fresh grain, as your meal offering of first fruits.

According to Milgram, this refers to barley, not wheat, as barley is not usually eaten in this manner.

The text does not refer to any festival in which such an offering is brought. The phrasing seems to imply that it is up to the individual to decide when to bring the offering "if" and not "when." However, if Leviticus does not have a date for this holiday and leaves it up to the individual farmer, then there is no reason not to identify this with the Omer offering.

(כו) וּבְי֣וֹם הַבִּכּוּרִ֗ים בְּהַקְרִ֨יבְכֶ֜ם מִנְחָ֤ה חֲדָשָׁה֙ לַֽיהוָ֔ה בְּשָׁבֻעֹ֖תֵיכֶ֑ם מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֥א תַעֲשֽׂוּ׃ (כז) וְהִקְרַבְתֶּ֨ם עוֹלָ֜ה לְרֵ֤יחַ נִיחֹ֙חַ֙ לַֽיהוָ֔ה פָּרִ֧ים בְּנֵי־בָקָ֛ר שְׁנַ֖יִם אַ֣יִל אֶחָ֑ד שִׁבְעָ֥ה כְבָשִׂ֖ים בְּנֵ֥י שָׁנָֽה׃ (כח) וּמִנְחָתָ֔ם סֹ֖לֶת בְּלוּלָ֣ה בַשָּׁ֑מֶן שְׁלֹשָׁ֤ה עֶשְׂרֹנִים֙ לַפָּ֣ר הָֽאֶחָ֔ד שְׁנֵי֙ עֶשְׂרֹנִ֔ים לָאַ֖יִל הָאֶחָֽד׃ (כט) עִשָּׂרוֹן֙ עִשָּׂר֔וֹן לַכֶּ֖בֶשׂ הָאֶחָ֑ד לְשִׁבְעַ֖ת הַכְּבָשִֽׂים׃ (ל) שְׂעִ֥יר עִזִּ֖ים אֶחָ֑ד לְכַפֵּ֖ר עֲלֵיכֶֽם׃ (לא) מִלְּבַ֞ד עֹלַ֧ת הַתָּמִ֛יד וּמִנְחָת֖וֹ תַּעֲשׂ֑וּ תְּמִימִ֥ם יִהְיוּ־לָכֶ֖ם וְנִסְכֵּיהֶֽם׃ (פ)
(26) On the day of the first fruits, your Feast of Weeks, when you bring an offering of new grain to the LORD, you shall observe a sacred occasion: you shall not work at your occupations. (27) You shall present a burnt offering of pleasing odor to the LORD: two bulls of the herd, one ram, seven yearling lambs. (28) The meal offering with them shall be of choice flour with oil mixed in, three-tenths of a measure for a bull, two-tenths for a ram, (29) and one-tenth for each of the seven lambs. (30) And there shall be one goat for expiation in your behalf. (31) You shall present them—see that they are without blemish—with their libations, in addition to the regular burnt offering and its meal offering.
(כו) וּבְי֣וֹם הַבִּכּוּרִ֗ים בְּהַקְרִ֨יבְכֶ֜ם מִנְחָ֤ה חֲדָשָׁה֙ לַֽיהוָ֔ה בְּשָׁבֻעֹ֖תֵיכֶ֑ם מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֥א תַעֲשֽׂוּ׃
(26) On the day of the first fruits, your Feast of Weeks, when you bring an offering of new grain to the LORD, you shall observe a sacred occasion: you shall not work at your occupations.

Again, this is not called a חג, unlike Sukkot and Matzot which are (see below). The name of the day is “The Day of Firstfruits” the same name as is given in Exodus 23, and probably was originally part of Exodus 34. The crux of this passage is “in your weeks.” This word has almost certainly been awkwardly inserted into the verse by a later author. The syntax of the word itself is unusual—why is it “your weeks.” Clearly, the gloss alludes to a count of sorts, but within Numbers what this count is is unclear, for Numbers has no other firstfruits festival from which to count.

(יז) וּבַחֲמִשָּׁ֨ה עָשָׂ֥ר י֛וֹם לַחֹ֥דֶשׁ הַזֶּ֖ה חָ֑ג שִׁבְעַ֣ת יָמִ֔ים מַצּ֖וֹת יֵאָכֵֽל׃
(17) and on the fifteenth day of that month a festival. Unleavened bread shall be eaten for seven days.

(12) On the fifteenth day of the seventh month, you shall observe a sacred occasion: you shall not work at your occupations.—Seven days you shall observe a festival of the LORD.—

(27) You shall present a burnt offering of pleasing odor to the LORD: two bulls of the herd, one ram, seven yearling lambs. (28) The meal offering with them shall be of choice flour with oil mixed in, three-tenths of a measure for a bull, two-tenths for a ram, (29) and one-tenth for each of the seven lambs. (30) And there shall be one goat for expiation in your behalf. (31) You shall present them—see that they are without blemish—with their libations, in addition to the regular burnt offering and its meal offering.

The very list of sacrifices implies the centralization of this holiday. Similar to the end of the passage in Leviticus, Numbers assumes that this holiday is observed by the priests in some either regional or national sanctuary and not just by farmers visiting the local priest.

(9) You shall count off seven weeks; start to count the seven weeks when the sickle is first put to the standing grain. (10) Then you shall observe the Feast of Weeks for the LORD your God, offering your freewill contribution according as the LORD your God has blessed you. (11) You shall rejoice before the LORD your God with your son and daughter, your male and female slave, the Levite in your communities, and the stranger, the fatherless, and the widow in your midst, at the place where the LORD your God will choose to establish His name.

Deuteronomy seems to be a combination of P and H, with its own particular Deuteronomic shift. Like H, it refers to a count of seven weeks. However, unlike H and more like P (or at least the oblique reference in P) it does not have any first holiday with a determined date. While in H both holidays could have been originally personal, every farmer bringing these offerings when his own harvest began, and later on regional, with everyone bringing the offerings on the Sunday following the beginning of the harvest and again at the end of the seven-week period, since D calls this a pilgrimage festival, a חג, the date must be the same for everyone. Thus, as often happens, the confusion in D is a result of their taking an older, personal or regional holiday, and imposing upon it a unified national pilgrimage.

(1) When you enter the land that the LORD your God is giving you as a heritage, and you possess it and settle in it, (2) you shall take some of every first fruit of the soil, which you harvest from the land that the LORD your God is giving you, put it in a basket and go to the place where the LORD your God will choose to establish His name. (3) You shall go to the priest in charge at that time and say to him, “I acknowledge this day before the LORD your God that I have entered the land that the LORD swore to our fathers to assign us.” (4) The priest shall take the basket from your hand and set it down in front of the altar of the LORD your God. (5) You shall then recite as follows before the LORD your God: “My father was a fugitive Aramean. He went down to Egypt with meager numbers and sojourned there; but there he became a great and very populous nation. (6) The Egyptians dealt harshly with us and oppressed us; they imposed heavy labor upon us. (7) We cried to the LORD, the God of our fathers, and the LORD heard our plea and saw our plight, our misery, and our oppression. (8) The LORD freed us from Egypt by a mighty hand, by an outstretched arm and awesome power, and by signs and portents. (9) He brought us to this place and gave us this land, a land flowing with milk and honey. (10) Wherefore I now bring the first fruits of the soil which You, O LORD, have given me.” You shall leave it before the LORD your God and bow low before the LORD your God. (11) And you shall enjoy, together with the Levite and the stranger in your midst, all the bounty that the LORD your God has bestowed upon you and your household.

Deuteronomy has an entirely different understanding of "bikkurim." Whereas ch. 16 does not call the harvest festival "bikkurim," ch. 26 has a different occasion for bringing first fruits. This first fruits festival does not seem to have a date nor does it mention any particular type of first fruits.

(לו) וּלְהָבִ֞יא אֶת־בִּכּוּרֵ֣י אַדְמָתֵ֗נוּ וּבִכּוּרֵ֛י כָּל־פְּרִ֥י כָל־עֵ֖ץ שָׁנָ֣ה בְשָׁנָ֑ה לְבֵ֖ית יְהוָֽה׃
(36) “And [we undertake] to bring to the House of the LORD annually the first fruits of our soil, and of every fruit of every tree;

Here too there does not seem to be a particular date on which the bikkurim must be brought.

(21) On the fourteenth day of the first month you shall have the passover sacrifice; and during a festival of seven days unleavened bread shall be eaten. (22) On that day, the prince shall provide a bull of sin offering on behalf of himself and of the entire population; (23) and during the seven days of the festival, he shall provide daily—for seven days—seven bulls and seven rams, without blemish, for a burnt offering to the LORD, and one goat daily for a sin offering. (24) He shall provide a meal offering of an ephah for each bull and an ephah for each ram, with a hin of oil to every ephah. (25) So, too, during the festival of the seventh month, for seven days from the fifteenth day on, he shall provide the same sin offerings, burnt offerings, meal offerings, and oil.

In Exodus 23 and 34 and Deuteronomy 16 we read of three pilgrimage festivals, but here in Ezekiel, only the spring and fall festival are included. Shavuot or Katzir is not mentioned. It may be that this holiday was not considered a national pilgrimage as late as Ezekiel's time.

We should note that there is no explicit reference to this holiday in the Tanakh outside of the Torah. This is not true for Sukkot or Matzot.

(י) וַיַּחֲנ֥וּ בְנֵֽי־יִשְׂרָאֵ֖ל בַּגִּלְגָּ֑ל וַיַּעֲשׂ֣וּ אֶת־הַפֶּ֡סַח בְּאַרְבָּעָה֩ עָשָׂ֨ר י֥וֹם לַחֹ֛דֶשׁ בָּעֶ֖רֶב בְּעַֽרְב֥וֹת יְרִיחֽוֹ׃ (יא) וַיֹּ֨אכְל֜וּ מֵעֲב֥וּר הָאָ֛רֶץ מִמָּֽחֳרַ֥ת הַפֶּ֖סַח מַצּ֣וֹת וְקָל֑וּי בְּעֶ֖צֶם הַיּ֥וֹם הַזֶּֽה׃ (יב) וַיִּשְׁבֹּ֨ת הַמָּ֜ן מִֽמָּחֳרָ֗ת בְּאָכְלָם֙ מֵעֲב֣וּר הָאָ֔רֶץ וְלֹא־הָ֥יָה ע֛וֹד לִבְנֵ֥י יִשְׂרָאֵ֖ל מָ֑ן וַיֹּאכְל֗וּ מִתְּבוּאַת֙ אֶ֣רֶץ כְּנַ֔עַן בַּשָּׁנָ֖ה הַהִֽיא׃ (ס)
(10) Encamped at Gilgal, in the steppes of Jericho, the Israelites offered the passover sacrifice on the fourteenth day of the month, toward evening. (11) On the day after the passover offering, on that very day, they ate of the produce of the country, unleavened bread and parched grain. (12) On that same day, when they ate of the produce of the land, the manna ceased. The Israelites got no more manna; that year they ate of the yield of the land of Canaan.

In this text they begin to eat parched grains on the first day of Matzot. This is only one day earlier then Pharisaic tradition begins and it might be an allusion to the interpretation of Shabbat as the 15th of the month.

Temple Scroll, Column 18

[And] you shall count off for yourselves from the day on which you carried to YHW[H] the new cereal offering, the bread of the first-fruits, seven weeks; [there will be] seven full weeks [up] to the day after the seventh sabbath. You shall count off fifty days, and [y]ou [shall] o[f]fer new wine for the libation… (19:11-14)

The wine festival is celebrated 50 days after the wheat festival. The date would be the third of the fifth month.

Temple Scroll 21:11-16

From this day [you] shall count off [for yourselves] seven times seven weeks. There will be forty-nine days, seven full weeks, up to the day after the seventh sabbath. You shall count off fifty days and you shall offer new oil from the dwelling places of the clans of the so[ns of Is]rael half a hin, one per clan, refined new oil, and they shall bring the first of the oil on to the altar of burnt-offerings, first produce (bikkurim) before YHWH…

The oil festival, fifty days after the wine festival. The date would be the 22nd of the sixth month.

(3) How would they do it [reap the omer]?The agents of the court used to go out on the day before the festival and tie the unreaped grain in bunches to make it the easier to reap. All the inhabitants of the towns near by assembled there, so that it might be reaped with a great demonstration. As soon as it became dark he says to them: “Has the sun set?” And they answer, “Yes.” “Has the sun set?” And they answer, “Yes.” “With this sickle?” And they answer, “Yes.” “With this sickle?” And they answer, “Yes.” “Into this basket?” And they answer, “Yes.” “Into this basket?” And they answer, “Yes.” On the Sabbath he says to them, “On this Sabbath?” And they answer, “Yes.” “On this Sabbath?” And they answer, “Yes.” “Shall I reap?” And they answer, “Reap.” “Shall I reap?” And they answer, “Reap.” He repeated every matter three times, and they answer, “yes, yes, yes.” And why all of this? Because of the Boethusians who held that the reaping of the omer was not to take place at the conclusion of the [first day of the] festival.

The rabbis do seem to be familiar with some ritual marking the beginning of the offering of the Omer.
