레위기 6:8 미슈나 참조: Mishnah Shekalim & Mishnah Zevachim

One who says: “Behold, I am obligated to bring wood”, he may not bring less than two logs. [If he says: “Behold, I am obligated to bring] frankincense”, he may not bring less than a handful of it. [If he says: “Behold, I am obligated to bring] gold”, he may not bring less than a gold denar. “On six [was inscribed] “for freewill-offerings”: What was done with the freewill-offerings? They would buy with them burnt-offerings, the flesh [of which] was for the name [of God] and the hides for the priests. The following is the midrash which was expounded by Yehoyada the high priest: “It is a guilt-offering; it is a guilt offering, it goes to the Lord” (Leviticus 5:19). This is the general rule: anything which is brought because of a sin or because of guilt, they should purchase with it burnt offerings, the flesh [of which] was for the name [of God] and the hides for the priests. Thus the two verses are fulfilled: a guilt offering for the Lord and a guilt offering for the priests, and it says: “Money brought as a guilt offering or as a sin offering was not deposited in the House of the Lord; it went to the priests” (II Kings 12:17).

Whenever the altar does not acquire its flesh, the priests do not acquire the hide, for it is said, “[And the priest that offers] any man’s olah [the priest shall have … the hide]” (Leviticus 7:8), [this means,] an olah which went up on the altar on behalf a man. If an olah was slaughtered under a different designation, although it does not count for its owner, its hide belongs to the priests. Whether [it be] a man’s olah or a woman's olah, the hide belong to the priests.
