Midras Imamat 23:10: Ein Yaakov (Glick Edition), Sifra, Kohelet Rabbah & Midrash Tanchuma Buber

We are taught in a Baraitha: R. Juda taught in the name of R. Akiba: "Why does the Torah command (Lev. 23, 10) a sheaf of the first fruits to be brought on the Passover? Because Passover is the season when judgment is passed with respect to grain, and the Holy One, praised be He! said: 'Offer before Me the first sheaf of grain on Passover, so that the grain on the fields may be blessed, unto you.' And why are the two loaves offered on the Pentecost? Because Pentecost is the season when judgment is passed with respect to the fruit of trees, and the Holy One, praised be He! said: 'Bring before Me two loaves on the Pentecost, so that I may bless the fruits of the tree.' Why was the ceremony of the offer of Libation performed on the Feast of Tabernacles? Thus said the Holy One, praised be He! 'Perform before Me the ceremony of Libation that the rains shall fall in due season.' The Holy One, praised be He! said further: 'Recite before Me [on New Year's Day] Malchioth, in which divine homage is alluded to; Zichronoth, [verses in which divine remembrance is alluded to]; and Shofroth [verses treating of the Shofar]: Malchioth, that you proclaim Me king; Zichronoth, that your remembrance for good may come before Me. And how [shall this be done]? By the sounding of the cornet.' " R. Abahu said: "Why is the cornet made of a ram's horn? The Holy One, praised be He! said: Sound before Me a cornet made of a ram's horn, that I may remember, for your sake, the offering of Isaac, the son of Abraham."

1) (Vayikra 14:34) ("When you come to the land of Canaan, which I give to you for a possession, and I put a plague-spot of leprosy in a house of the land of your possession,") "When you come": I might think (that this applies) when they come to trans-Jordan; it is, therefore, written "to the land" — to the distinctive land (of Israel).

1) (Vayikra 23:10) ("Speak to the children of Israel and say to them: When you come to the land which I give to you and you reap its harvest, you shall bring an omer (one-tenth of an ephah) of the first of your harvest to the Cohein.") I might think, when they came to trans-Jordan; it is, therefore, written "the land" — the distinctive land.
