Leviticus 7:21-25

²¹And he that hath touched the uncleanness of man, or of beast, or of any thing that can defile, and shall eat of such kind of flesh, shall be cut off from his people.

²²And the Lord spoke to Moses, saying:

²³Say to the children of Israel: The fat of a sheep, and of an ox, and of a goat you shall not eat.

²⁴The fat of a carcass that hath died of itself, and of a beast that was caught by another beast, you shall have for divers uses.

²⁵If any man eat the fat that should be offered for the burnt sacrifice of the Lord, he shall perish out of his people.
