Leviticus 2:14

ואם תקריב AND IF (according to Rashi, AND “WHEN”) THOU OFFER [A MEAL-OFFERING OF FIRST FRUITS] — אם here has the meaning of כי, “when”, for this (the offering of the מנחת בכורים) is not optional, since Scripture is speaking of the meal-offering of the “Omer” which is obligatory. Similar is אם in the phrase (Numbers 36:4) ואם יהיה היובל which means: “when the jubilee will be”, not: “if the jubilee will be”, since it is bound to come (cf. Sifra, Vayikra Dibbura d'Nedavah, Section 13 2; see also Rashi on Exodus 20:22). מנחת בכורים THE MEAL-OFFERING OF FIRSTFRUITS — Scripture is speaking here of the meal-offering of the “Omer” (Leviticus 23:10) which is brought when the grain is in the green ears ,(אביב), i.e.. at the time of the ripening of the grain, and which was brought of barley, for it states here “אביב”, and there, too, (Exodus 9:31) it slates “for the barley was in the ears (אביב)” (Sifra, Vayikra Dibbura d'Nedavah, Section 13 4; Menachot 68b). קלוי באש PARCHED BY THE FIRE It is thus described because they roast it on the fire in the “tube of the grain-parchers (אביב של קלאים)”, for unless it was treated thus it could not be ground in the mill because it was fresh, as the term אביב green, fresh suggests (cf. Rashi on Exodus 9:31). גרש כרמל means broken (גרוש) whilst it was yet fresh (כרמל). גרש is an expression for breaking and grinding. — He ground it in a grit-mill. — גרש has the same meaning as the verb in (Lamentations 3:16) “and He hath broken (ויגרס) [my teeth] with gravel-stones”; and similarly (Psalms 119:20) “My soul is broken (גרסה). כרמל — i. e., broken whilst the husk (כר) is yet full (מלא) (according to this כרמל is a word compounded of כר and מל) — when the crop is yet fresh and full in its stalks; for this reason the fresh ears are called כרמל. Similar is, (2 Kings 4:42) “and full ears of corn (כרמל) in the husk thereof”.

וְאִם־תַּקְרִ֛יב מִנְחַ֥ת בִּכּוּרִ֖ים לַיהֹוָ֑ה אָבִ֞יב קָל֤וּי בָּאֵשׁ֙ גֶּ֣רֶשׂ כַּרְמֶ֔ל תַּקְרִ֕יב אֵ֖ת מִנְחַ֥ת בִּכּוּרֶֽיךָ׃

And if thou offer a meal offering of thy firstfruits to the Lord, thou shalt offer for the meal offering of thy firstfruits ears of corn dried by the fire, corn beaten out of fresh ears.
