Kapłańska 16:8 Midrasz: Sifra, Midrash Aggadah & Pirkei DeRabbi Eliezer

2) (Vayikra 16:8) ("And Aaron shall place on the two he-goats lots, one lot for the L–rd, and the other lot for Azazel." "And Aaron shall place on the two he-goats lots": lots of any substance. I might think two on this and two on the other; it is, therefore, written "a lot for the L–rd and a lot for Azazel." I might think "for the L–rd and for Azazel" on this, and "for the L–rd and for Azazel" on the other; it is, therefore, written "one lot for the L–rd and one lot for Azazel." There is only one for Azazel.

3) If so, why is "lots" written? That they both be alike: That one not be large, and the other small; one of silver and the other of gold; one of marble and the other of box-wood.

Aaron shall place lots on the two goats... (Leviticus 16:8) Why should he do this, and walk that goat to Azazel, and bring him to a great, hard mountain, and push him until he is cut up into many pieces? It is to teach you that we ask from the Creator that just like this goat, which is bearing the sins of Israel on it, just like the goat falls and becomes many pieces, and there remains of it no substance and no benefit, so too, you, King of Kings of Kings, the Holy Blessed One, let fall our transgressions, and may they be lost from your book, and may they have no standing. And there are those who explain that Israel says: leave the evil inclination, and cast it out [hashlikhu] from upon you, like this goat that is sent out [mishtaleach], and about that is said, the goat bore on it all their sins (of the children of Israel) [to a land cut off] (Leviticus 16:22).
