Exodus 34:22

בכורי קציר חטים [THE FESTIVAL] OF THE FIRST OF THE WHEAT HARVEST — It is so called because on it you offer the two loaves of wheat (Leviticus 23:17). בכורי OF THE FIRST [OF THE WHEAT HARVEST] — It is so called because it (the offering of the two loaves) is the first meal offering which is brought in the Temple of the new wheat crop; for the meal offering of the Omer which had already been brought on Passover was of barley (Menachot 84a). וחג האסיף AND THE FESTIVAL OF INGATHERING — the festival that falls at the time of the year when you gather in thy produce from the field into the barns. The word אסף here means bringing in (and not, collecting), as (Deuteronomy 22:2) “thou shalt gather it (ואספתו) into thine house” (cf. Rashi on Exodus 23:16 and on Genesis 49:29). תקופת השנה lit., [THE FESTIVAL …] THE YEARS CIRCUIT — i. e. the festival at the coming round of the year — at the beginning of the coming (the new) year. תקופת is a term denoting going round.

וְחַ֤ג שָׁבֻעֹת֙ תַּעֲשֶׂ֣ה לְךָ֔ בִּכּוּרֵ֖י קְצִ֣יר חִטִּ֑ים וְחַג֙ הָֽאָסִ֔יף תְּקוּפַ֖ת הַשָּׁנָֽה׃

And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year’s end.
