(1) The LORD spoke to Moses in the wilderness of Sinai, on the first new moon of the second year following the exodus from the land of Egypt, saying: (2) Let the Israelite people offer the passover sacrifice at its set time: (3) you shall offer it on the fourteenth day of this month, at twilight, at its set time; you shall offer it in accordance with all its rules and rites. (4) Moses instructed the Israelites to offer the passover sacrifice; (5) and they offered the passover sacrifice in the first month, on the fourteenth day of the month, at twilight, in the wilderness of Sinai. Just as the LORD had commanded Moses, so the Israelites did. (6) But there were some men who were unclean by reason of a corpse and could not offer the passover sacrifice on that day. Appearing that same day before Moses and Aaron, (7) those men said to them, “Unclean though we are by reason of a corpse, why must we be debarred from presenting the LORD’s offering at its set time with the rest of the Israelites?” (8) Moses said to them, “Stand by, and let me hear what instructions the LORD gives about you.” (9) And the LORD spoke to Moses, saying: (10) Speak to the Israelite people, saying: When any of you or of your posterity who are defiled by a corpse or are on a long journey would offer a passover sacrifice to the LORD, (11) they shall offer it in the second month, on the fourteenth day of the month, at twilight. They shall eat it with unleavened bread and bitter herbs, (12) and they shall not leave any of it over until morning. They shall not break a bone of it. They shall offer it in strict accord with the law of the passover sacrifice. (13) But if a man who is clean and not on a journey refrains from offering the passover sacrifice, that person shall be cut off from his kin, for he did not present the LORD’s offering at its set time; that man shall bear his guilt. (14) And when a stranger who resides with you would offer a passover sacrifice to the LORD, he must offer it in accordance with the rules and rites of the passover sacrifice. There shall be one law for you, whether stranger or citizen of the country.

(15) On the day that the Tabernacle was set up, the cloud covered the Tabernacle, the Tent of the Pact; and in the evening it rested over the Tabernacle in the likeness of fire until morning. (16) It was always so: the cloud covered it, appearing as fire by night. (17) And whenever the cloud lifted from the Tent, the Israelites would set out accordingly; and at the spot where the cloud settled, there the Israelites would make camp. (18) At a command of the LORD the Israelites broke camp, and at a command of the LORD they made camp: they remained encamped as long as the cloud stayed over the Tabernacle. (19) When the cloud lingered over the Tabernacle many days, the Israelites observed the LORD’s mandate and did not journey on. (20) At such times as the cloud rested over the Tabernacle for but a few days, they remained encamped at a command of the LORD, and broke camp at a command of the LORD. (21) And at such times as the cloud stayed from evening until morning, they broke camp as soon as the cloud lifted in the morning. Day or night, whenever the cloud lifted, they would break camp. (22) Whether it was two days or a month or a year—however long the cloud lingered over the Tabernacle—the Israelites remained encamped and did not set out; only when it lifted did they break camp. (23) On a sign from the LORD they made camp and on a sign from the LORD they broke camp; they observed the LORD’s mandate at the LORD’s bidding through Moses.

When are we supposed to do the Korban Pesach?

(כה) וְהָיָ֞ה כִּֽי־תָבֹ֣אוּ אֶל־הָאָ֗רֶץ אֲשֶׁ֨ר יִתֵּ֧ן יקוק לָכֶ֖ם כַּאֲשֶׁ֣ר דִּבֵּ֑ר וּשְׁמַרְתֶּ֖ם אֶת־הָעֲבֹדָ֥ה הַזֹּֽאת׃

(25) And when you enter the land that the LORD will give you, as He has promised, you shall observe this rite.

Is Sefer Bamidbar in order? No way! Here is the opening passuk of Sefer Bamidbar!

(א) וַיְדַבֵּ֨ר יקוק אֶל־מֹשֶׁ֛ה בְּמִדְבַּ֥ר סִינַ֖י בְּאֹ֣הֶל מוֹעֵ֑ד בְּאֶחָד֩ לַחֹ֨דֶשׁ הַשֵּׁנִ֜י בַּשָּׁנָ֣ה הַשֵּׁנִ֗ית לְצֵאתָ֛ם מֵאֶ֥רֶץ מִצְרַ֖יִם לֵאמֹֽר׃

(1) On the first day of the second month, in the second year following the exodus from the land of Egypt, the LORD spoke to Moses in the wilderness of Sinai, in the Tent of Meeting, saying:

"Don't count the Leviim." ...

(לג) וְהַ֨לְוִיִּ֔ם לֹ֣א הָתְפָּקְד֔וּ בְּת֖וֹךְ בְּנֵ֣י יִשְׂרָאֵ֑ל כַּאֲשֶׁ֛ר צִוָּ֥ה יקוק אֶת־מֹשֶֽׁה׃ (לד) וַֽיַּעֲשׂ֖וּ בְּנֵ֣י יִשְׂרָאֵ֑ל כְּ֠כֹל אֲשֶׁר־צִוָּ֨ה יקוק אֶת־מֹשֶׁ֗ה כֵּֽן־חָנ֤וּ לְדִגְלֵיהֶם֙ וְכֵ֣ן נָסָ֔עוּ אִ֥ישׁ לְמִשְׁפְּחֹתָ֖יו עַל־בֵּ֥ית אֲבֹתָֽיו׃

(33) The Levites, however, were not recorded among the Israelites, as the LORD had commanded Moses. (34) The Israelites did accordingly; just as the LORD had commanded Moses, so they camped by their standards, and so they marched, each with his clan according to his ancestral house.

... "Actually, let's count the Leviim." What is going on?

(י) וְאֶת־אַהֲרֹ֤ן וְאֶת־בָּנָיו֙ תִּפְקֹ֔ד וְשָׁמְר֖וּ אֶת־כְּהֻנָּתָ֑ם וְהַזָּ֥ר הַקָּרֵ֖ב יוּמָֽת׃ (פ)

(10) You shall make Aaron and his sons responsible for observing their priestly duties; and any outsider who encroaches shall be put to death.
When did the census of the Leviim take place? CLEARLY by Rosh Chodesh Nissan this was completed because of the text below.

(ד) וַיֹּ֥אמֶר יקוק אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃ (ה) קַ֚ח מֵֽאִתָּ֔ם וְהָי֕וּ לַעֲבֹ֕ד אֶת־עֲבֹדַ֖ת אֹ֣הֶל מוֹעֵ֑ד וְנָתַתָּ֤ה אוֹתָם֙ אֶל־הַלְוִיִּ֔ם אִ֖ישׁ כְּפִ֥י עֲבֹדָתֽוֹ׃ (ו) וַיִּקַּ֣ח מֹשֶׁ֔ה אֶת־הָעֲגָלֹ֖ת וְאֶת־הַבָּקָ֑ר וַיִּתֵּ֥ן אוֹתָ֖ם אֶל־הַלְוִיִּֽם׃ (ז) אֵ֣ת ׀ שְׁתֵּ֣י הָעֲגָלֹ֗ת וְאֵת֙ אַרְבַּ֣עַת הַבָּקָ֔ר נָתַ֖ן לִבְנֵ֣י גֵרְשׁ֑וֹן כְּפִ֖י עֲבֹדָתָֽם׃ (ח) וְאֵ֣ת ׀ אַרְבַּ֣ע הָעֲגָלֹ֗ת וְאֵת֙ שְׁמֹנַ֣ת הַבָּקָ֔ר נָתַ֖ן לִבְנֵ֣י מְרָרִ֑י כְּפִי֙ עֲבֹ֣דָתָ֔ם בְּיַד֙ אִֽיתָמָ֔ר בֶּֽן־אַהֲרֹ֖ן הַכֹּהֵֽן׃ (ט) וְלִבְנֵ֥י קְהָ֖ת לֹ֣א נָתָ֑ן כִּֽי־עֲבֹדַ֤ת הַקֹּ֙דֶשׁ֙ עֲלֵהֶ֔ם בַּכָּתֵ֖ף יִשָּֽׂאוּ׃

(4) the LORD said to Moses: (5) Accept these from them for use in the service of the Tent of Meeting, and give them to the Levites according to their respective services. (6) Moses took the carts and the oxen and gave them to the Levites. (7) Two carts and four oxen he gave to the Gershonites, as required for their service, (8) and four carts and eight oxen he gave to the Merarites, as required for their service—under the direction of Ithamar son of Aaron the priest. (9) But to the Kohathites he did not give any; since theirs was the service of the [most] sacred objects, their porterage was by shoulder.

List of Questions:

  1. Ordering of Sefer Bamidbar in general:

    (1A) Why is the Pesach Sheni story juxtaposed with the (clearly retrospective) story of clouds and fire protections and how they would travel?


    (1B) Given that even according to the Ramban - the staunchest supporter of "the Torah IS in chronological order" - Sefer Bamidbar is certainly OUT of order. So why is Pesach Sheni placed here?

    (1C) Why is the story of the Levi census so odd? After all, the Levi census is wrapped up in this whole chronological mess. Furthermore, what might this have to do with Pesach Sheni?

  2. Why were we commanded to (and actually bring) the Korban Pesach in Year #2 if the Korban Pesach, per the law, is supposed to be brought only when we got into the land?

While the answer to the "Bamidbar Chronological Problem" is a shiur unto itself, we will attempt to answer at LEAST why the Pesach Sheni story is here.

To answer all these questions we need to look at one more Bamidbar story.............Korach. WHEN DID THIS STORY TAKE PLACE?

What is the "Korach Test"? The ketoret!

(טז) וַיֹּ֤אמֶר מֹשֶׁה֙ אֶל־קֹ֔רַח אַתָּה֙ וְכָל־עֲדָ֣תְךָ֔ הֱי֖וּ לִפְנֵ֣י יקוק אַתָּ֥ה וָהֵ֛ם וְאַהֲרֹ֖ן מָחָֽר׃ (יז) וּקְח֣וּ ׀ אִ֣ישׁ מַחְתָּת֗וֹ וּנְתַתֶּ֤ם עֲלֵיהֶם֙ קְטֹ֔רֶת וְהִקְרַבְתֶּ֞ם לִפְנֵ֤י יקוק אִ֣ישׁ מַחְתָּת֔וֹ חֲמִשִּׁ֥ים וּמָאתַ֖יִם מַחְתֹּ֑ת וְאַתָּ֥ה וְאַהֲרֹ֖ן אִ֥ישׁ מַחְתָּתֽוֹ׃ (יח) וַיִּקְח֞וּ אִ֣ישׁ מַחְתָּת֗וֹ וַיִּתְּנ֤וּ עֲלֵיהֶם֙ אֵ֔שׁ וַיָּשִׂ֥ימוּ עֲלֵיהֶ֖ם קְטֹ֑רֶת וַֽיַּעַמְד֗וּ פֶּ֛תַח אֹ֥הֶל מוֹעֵ֖ד וּמֹשֶׁ֥ה וְאַהֲרֹֽן׃

(16) And Moses said to Korah, “Tomorrow, you and all your company appear before the LORD, you and they and Aaron. (17) Each of you take his fire pan and lay incense on it, and each of you bring his fire pan before the LORD, two hundred and fifty fire pans; you and Aaron also [bring] your fire pans.” (18) Each of them took his fire pan, put fire in it, laid incense on it, and took his place at the entrance of the Tent of Meeting, as did Moses and Aaron.

Indeed what happened to Korach's followers?

(לה) וְאֵ֥שׁ יָצְאָ֖ה מֵאֵ֣ת יקוק וַתֹּ֗אכַל אֵ֣ת הַחֲמִשִּׁ֤ים וּמָאתַ֙יִם֙ אִ֔ישׁ מַקְרִיבֵ֖י הַקְּטֹֽרֶת׃

(35) And a fire went forth from the LORD and consumed the two hundred and fifty men offering the incense.
If you know this story - you have to be crazy to use the ketoret as a "test".

(א) וַיִּקְח֣וּ בְנֵֽי־אַ֠הֲרֹן נָדָ֨ב וַאֲבִיה֜וּא אִ֣ישׁ מַחְתָּת֗וֹ וַיִּתְּנ֤וּ בָהֵן֙ אֵ֔שׁ וַיָּשִׂ֥ימוּ עָלֶ֖יהָ קְטֹ֑רֶת וַיַּקְרִ֜בוּ לִפְנֵ֤י יקוק אֵ֣שׁ זָרָ֔ה אֲשֶׁ֧ר לֹ֦א צִוָּ֖ה אֹתָֽם׃ (ב) וַתֵּ֥צֵא אֵ֛שׁ מִלִּפְנֵ֥י יקוק וַתֹּ֣אכַל אוֹתָ֑ם וַיָּמֻ֖תוּ לִפְנֵ֥י יקוק׃

(1) Now Aaron’s sons Nadab and Abihu each took his fire pan, put fire in it, and laid incense on it; and they offered before the LORD alien fire, which He had not enjoined upon them. (2) And fire came forth from the LORD and consumed them; thus they died at the instance of the LORD.
What happened in the aftermath of the Korach story? A PLAGUE.

(ו) וַיִּלֹּ֜נוּ כָּל־עֲדַ֤ת בְּנֵֽי־יִשְׂרָאֵל֙ מִֽמָּחֳרָ֔ת עַל־מֹשֶׁ֥ה וְעַֽל־אַהֲרֹ֖ן לֵאמֹ֑ר אַתֶּ֥ם הֲמִתֶּ֖ם אֶת־עַ֥ם יקוק׃ (ז) וַיְהִ֗י בְּהִקָּהֵ֤ל הָֽעֵדָה֙ עַל־מֹשֶׁ֣ה וְעַֽל־אַהֲרֹ֔ן וַיִּפְנוּ֙ אֶל־אֹ֣הֶל מוֹעֵ֔ד וְהִנֵּ֥ה כִסָּ֖הוּ הֶעָנָ֑ן וַיֵּרָ֖א כְּב֥וֹד יקוק׃ (ח) וַיָּבֹ֤א מֹשֶׁה֙ וְאַהֲרֹ֔ן אֶל־פְּנֵ֖י אֹ֥הֶל מוֹעֵֽד׃ (פ) (ט) וַיְדַבֵּ֥ר יקוק אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃ (י) הֵרֹ֗מּוּ מִתּוֹךְ֙ הָעֵדָ֣ה הַזֹּ֔את וַאֲכַלֶּ֥ה אֹתָ֖ם כְּרָ֑גַע וַֽיִּפְּל֖וּ עַל־פְּנֵיהֶֽם׃ (יא) וַיֹּ֨אמֶר מֹשֶׁ֜ה אֶֽל־אַהֲרֹ֗ן קַ֣ח אֶת־הַ֠מַּחְתָּה וְתֶן־עָלֶ֨יהָ אֵ֜שׁ מֵעַ֤ל הַמִּזְבֵּ֙חַ֙ וְשִׂ֣ים קְטֹ֔רֶת וְהוֹלֵ֧ךְ מְהֵרָ֛ה אֶל־הָעֵדָ֖ה וְכַפֵּ֣ר עֲלֵיהֶ֑ם כִּֽי־יָצָ֥א הַקֶּ֛צֶף מִלִּפְנֵ֥י יקוק הֵחֵ֥ל הַנָּֽגֶף׃ (יב) וַיִּקַּ֨ח אַהֲרֹ֜ן כַּאֲשֶׁ֣ר ׀ דִּבֶּ֣ר מֹשֶׁ֗ה וַיָּ֙רָץ֙ אֶל־תּ֣וֹך הַקָּהָ֔ל וְהִנֵּ֛ה הֵחֵ֥ל הַנֶּ֖גֶף בָּעָ֑ם וַיִּתֵּן֙ אֶֽת־הַקְּטֹ֔רֶת וַיְכַפֵּ֖ר עַל־הָעָֽם׃ (יג) וַיַּעֲמֹ֥ד בֵּֽין־הַמֵּתִ֖ים וּבֵ֣ין הַֽחַיִּ֑ים וַתֵּעָצַ֖ר הַמַּגֵּפָֽה׃ (יד) וַיִּהְי֗וּ הַמֵּתִים֙ בַּמַּגֵּפָ֔ה אַרְבָּעָ֥ה עָשָׂ֛ר אֶ֖לֶף וּשְׁבַ֣ע מֵא֑וֹת מִלְּבַ֥ד הַמֵּתִ֖ים עַל־דְּבַר־קֹֽרַח׃ (טו) וַיָּ֤שָׁב אַהֲרֹן֙ אֶל־מֹשֶׁ֔ה אֶל־פֶּ֖תַח אֹ֣הֶל מוֹעֵ֑ד וְהַמַּגֵּפָ֖ה נֶעֱצָֽרָה׃ (פ)

(6) Next day the whole Israelite community railed against Moses and Aaron, saying, “You two have brought death upon the LORD’s people!” (7) But as the community gathered against them, Moses and Aaron turned toward the Tent of Meeting; the cloud had covered it and the Presence of the LORD appeared. (8) When Moses and Aaron reached the Tent of Meeting, (9) the LORD spoke to Moses, saying, (10) “Remove yourselves from this community, that I may annihilate them in an instant.” They fell on their faces. (11) Then Moses said to Aaron, “Take the fire pan, and put on it fire from the altar. Add incense and take it quickly to the community and make expiation for them. For wrath has gone forth from the LORD: the plague has begun!” (12) Aaron took it, as Moses had ordered, and ran to the midst of the congregation, where the plague had begun among the people. He put on the incense and made expiation for the people; (13) he stood between the dead and the living until the plague was checked. (14) Those who died of the plague came to fourteen thousand and seven hundred, aside from those who died on account of Korah. (15) Aaron then returned to Moses at the entrance of the Tent of Meeting, since the plague was checked.

Now let's tie all these things up.......

Q: What is the Korban Pesach to the Jews in the desert in Year #2?A: A plague stopper! Protection!

(יב) וְעָבַרְתִּ֣י בְאֶֽרֶץ־מִצְרַיִם֮ בַּלַּ֣יְלָה הַזֶּה֒ וְהִכֵּיתִ֤י כָל־בְּכוֹר֙ בְּאֶ֣רֶץ מִצְרַ֔יִם מֵאָדָ֖ם וְעַד־בְּהֵמָ֑ה וּבְכָל־אֱלֹקֵ֥י מִצְרַ֛יִם אֶֽעֱשֶׂ֥ה שְׁפָטִ֖ים אֲנִ֥י יקוק׃ (יג) וְהָיָה֩ הַדָּ֨ם לָכֶ֜ם לְאֹ֗ת עַ֤ל הַבָּתִּים֙ אֲשֶׁ֣ר אַתֶּ֣ם שָׁ֔ם וְרָאִ֙יתִי֙ אֶת־הַדָּ֔ם וּפָסַחְתִּ֖י עֲלֵכֶ֑ם וְלֹֽא־יִֽהְיֶ֨ה בָכֶ֥ם נֶ֙גֶף֙ לְמַשְׁחִ֔ית בְּהַכֹּתִ֖י בְּאֶ֥רֶץ מִצְרָֽיִם׃

(12) For that night I will go through the land of Egypt and strike down every first-born in the land of Egypt, both man and beast; and I will mete out punishments to all the gods of Egypt, I the LORD. (13) And the blood on the houses where you are staying shall be a sign for you: when I see the blood I will pass over you, so that no plague will destroy you when I strike the land of Egypt.

(כה) וְהָיָ֞ה כִּֽי־תָבֹ֣אוּ אֶל־הָאָ֗רֶץ אֲשֶׁ֨ר יִתֵּ֧ן יקוק לָכֶ֖ם כַּאֲשֶׁ֣ר דִּבֵּ֑ר וּשְׁמַרְתֶּ֖ם אֶת־הָעֲבֹדָ֥ה הַזֹּֽאת׃ (כו) וְהָיָ֕ה כִּֽי־יֹאמְר֥וּ אֲלֵיכֶ֖ם בְּנֵיכֶ֑ם מָ֛ה הָעֲבֹדָ֥ה הַזֹּ֖את לָכֶֽם׃ (כז) וַאֲמַרְתֶּ֡ם זֶֽבַח־פֶּ֨סַח ה֜וּא לַֽיקוק אֲשֶׁ֣ר פָּ֠סַח עַל־בָּתֵּ֤י בְנֵֽי־יִשְׂרָאֵל֙ בְּמִצְרַ֔יִם בְּנָגְפּ֥וֹ אֶת־מִצְרַ֖יִם וְאֶת־בָּתֵּ֣ינוּ הִצִּ֑יל וַיִּקֹּ֥ד הָעָ֖ם וַיִּֽשְׁתַּחֲוּֽוּ׃

(25) And when you enter the land that the LORD will give you, as He has promised, you shall observe this rite. (26) And when your children ask you, ‘What do you mean by this rite?’ (27) you shall say, ‘It is the passover sacrifice to the LORD, because He passed over the houses of the Israelites in Egypt when He smote the Egyptians, but saved our houses.’” The people then bowed low in homage.
When do you do a census? After a PLAGUE. (See end of Bamidbar.)

(א) וַיְהִ֖י אַחֲרֵ֣י הַמַּגֵּפָ֑ה (פ) וַיֹּ֤אמֶר יקוק אֶל־מֹשֶׁ֔ה וְאֶ֧ל אֶלְעָזָ֛ר בֶּן־אַהֲרֹ֥ן הַכֹּהֵ֖ן לֵאמֹֽר׃ (ב) שְׂא֞וּ אֶת־רֹ֣אשׁ ׀ כָּל־עֲדַ֣ת בְּנֵי־יִשְׂרָאֵ֗ל מִבֶּ֨ן עֶשְׂרִ֥ים שָׁנָ֛ה וָמַ֖עְלָה לְבֵ֣ית אֲבֹתָ֑ם כָּל־יֹצֵ֥א צָבָ֖א בְּיִשְׂרָאֵֽל׃

(1) When the plague was over, the LORD said to Moses and to Eleazar son of Aaron the priest, (2) “Take a census of the whole Israelite community from the age of twenty years up, by their ancestral houses, all Israelites able to bear arms.”
