Midrash su Levitico 16:9

1) (Vayikra 16:5) ("And from the congregation of the children of Israel he shall take two he-goats for a sin-offering and one ram for a burnt-offering.") "And from the congregation of the children of Israel": They must be from (i.e., are funded by) the community. "he shall take two he-goats": The minimum of he-goats is two. Why, then, is it written "two"? That they be alike (in all respects). And whence is it derived that even if they are not alike, they are (nevertheless) valid? From "he-goat" (Vayikra 16:9); "he-goat" (Vayikra 16:10), (connoting de facto validity with) any he-goat.

(Lev. 14:2:) “In the day of his cleansing.” [With what?]²⁰Lev. R. 16:7. With (according to vs. 4) “two live clean birds.” How is his offering different from all [other] offerings? It is simply that he has spoken slander. Therefore, the text says that his sacrifice is two birds, because they (like slanderers) carry their voices. (Lev. 14:4, cont.:) “And cedar wood.” In the case of the cedar, no tree is taller (gevoha) than that one; so because [the leper] has exalted (gevoha) himself like a cedar, [he has had] the leprosy come upon him.²¹PRK 4:3. Thus Simeon ben Eleazar has said, “Leprosy comes on account of haughtiness, for so you find in the case of Uzziah (in II Chron. 26:16), ‘But when he was strong, he grew so arrogant that he acted corruptly,’ and it is written (in II Chron. 26:19), ‘but during his anger with the priests, leprosy appeared on his forehead.’” (Lev. 14:4, cont.:) “And with hyssop.” Among the trees there is none [as short] as the hyssop. Because [the leper] has lowered himself, [leprosy] is therefore cured through the hyssop. (Lev. 14:5:) “[Then the priest shall give a command] to kill one bird.” Why kill one and release one? It is simply that, if he has repented, the leprosy shall not return upon him.²²Cf. Lev. 16:9. (Lev. 14:2:) “[This shall be the law of the leper in the day of his cleansing:] He shall be brought unto the priest.” What is the meaning of “He shall be brought (rt.: bw')?” He comes (rt.: bw'). Why? Because everything is far off and separated from him, for so David says (in Ps. 38:12), “My friends and companions stand aloof from my affliction, and my kinfolk stand far off.” So also it says (in Lev. 13:46), “he shall dwell alone; his dwelling shall be outside the camp,” outside the camp of Israel. It is therefore stated (in Lev. 14:2), “he shall be brought (rt.: bw'),” [meaning] he comes (rt.: bw').

4) (Vayikra 16:9) ("And Aaron shall present the he-goat on which the lot came up for the L–rd, and he shall make it a sin-offering.") "And Aaron shall present the he-goat on which is the lot for the L–rd": I might think that he places it on its back; it is, therefore, written "on which the lot came up for it" — It came up for His name from the ballot box.
