(א) אֵלּוּ דְבָרִים שֶׁאֵין לָהֶם שִׁעוּר. הַפֵּאָה, וְהַבִּכּוּרִים, וְהָרֵאָיוֹן, וּגְמִילוּת חֲסָדִים, וְתַלְמוּד תּוֹרָה.
(1) These are the things that have no measure: Peah [corner of the field which, while harvesting, must be left for the poor], Bikurim [First-fruits that must be brought to the Temple and given to the priest], the appearance-sacrifice [brought to the Temple on Pilgrimage Festivals], acts of kindness, and the study of the Torah.
(טז) וְחַ֤ג הַקָּצִיר֙ בִּכּוּרֵ֣י מַעֲשֶׂ֔יךָ אֲשֶׁ֥ר תִּזְרַ֖ע בַּשָּׂדֶ֑ה וְחַ֤ג הָֽאָסִף֙ בְּצֵ֣את הַשָּׁנָ֔ה בְּאָסְפְּךָ֥ אֶֽת־מַעֲשֶׂ֖יךָ מִן־הַשָּׂדֶֽה׃ (יז) שָׁלֹ֥שׁ פְּעָמִ֖ים בַּשָּׁנָ֑ה יֵרָאֶה֙ כָּל־זְכ֣וּרְךָ֔ אֶל־פְּנֵ֖י הָאָדֹ֥ן ׀ יְהוָֽה׃
(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. (17) Three times a year all your males shall appear before the Sovereign, the LORD.
(א) וחג הקציר. הוּא חַג שָׁבוּעוֹת:
(1) וחג הקציר AND THE FESTIVAL OF HARVEST — this is the Feast of Weeks
(ב) בְּאַרְבָּעָה פְרָקִים הָעוֹלָם נִדּוֹן, בְּפֶסַח עַל הַתְּבוּאָה, בַּעֲצֶרֶת עַל פֵּרוֹת הָאִילָן, בְּרֹאשׁ הַשָּׁנָה כָּל בָּאֵי הָעוֹלָם עוֹבְרִין לְפָנָיו כִּבְנֵי מָרוֹן, שֶׁנֶּאֱמַר (תהלים לג) הַיּוֹצֵר יַחַד לִבָּם, הַמֵּבִין אֶל כָּל מַעֲשֵׂיהֶם. וּבֶחָג נִדּוֹנִין עַל הַמָּיִם:
(2) At four times the world is judged: On Pesach, for the crops. On Shavuot, for the fruits of the tree. On Rosh Hashnah, all the world passes before Him like sheep, as it says, "He that fashioneth the hearts of them all, that considereth all their doings." (Psalms 33:15) And on Sukkot, they are judged for the water.
Rabbi Aryeh Frimer, "The Message of Shavuot":
In contradistinction to the other regalim, Shavuot has no specific holiday-related commandments or rituals for the individual – certainly nothing like the Seder of Pesah, or the Lulav and Sukka of Sukkot. On the contrary, its content is perhaps more intellectual - an attempt to create a Jewish weltanschauung (world view). As outlined above, the message of Shavuot is comprised of three parts: the need to recognize and acknowledge our ongoing dependence on the G-d of Creation, the centrality of Sinaitic revelation and Torah as a dynamic experience and the pivotal importance of gemillut hassadim.
Religion Allied to Progress - Rabbi Samson Raphael Hirsch (1854)
Comparisons are futile, Judaism is not a religion, the synagogue is not a church, and the rabbi is not a priest. Judaism is not a mere adjunct to life: it comprises all of life. To be a Jew is not a mere part, it is the sum total of our task in life. To be a Jew in the synagogue and in the kitchen, in the field and in the warehouse, in the office and the pulpit, as father and mother, as servant and master, as man and as citizen, with one's thoughts, in word and in deed, in enjoyment and privation, with the needle and the engraving tool, with the pen and the chisel -- that is what it means to be a Jew. An entire life supported by the Divine Idea and lived and brought to fulfilment according to the Divine Will.
