Leviticus 7:18–21

18 If any of the flesh of the sacrifice of his peace offering is eaten on the third day, he who offers it shall not be accepted, neither shall it be credited to him. It is ctainted, and he who eats of it shall bear his iniquity.

19 “Flesh that touches any unclean thing shall not be eaten. It shall be burned up with fire. All who are clean may eat flesh, 20 but the person who eats of the flesh of the sacrifice of the Lord’s peace offerings dwhile an uncleanness is on him, that person shall be cut off from his people. 21 And if anyone touches an unclean thing, whether ehuman uncleanness or an funclean beast or any gunclean detestable creature, and then eats some flesh from the sacrifice of the Lord’s peace offerings, that person shall be cut off from his people.”
