Leviticus 7:15-21

15And the flesh of the sacrifice of his peace-offering of thanksgiving shall be eaten the same day that it is presented; he shall not let any of it remain until the morning.

16And if the sacrifice of his offering be a vow, or voluntary, it shall be eaten the same day that he presented his sacrifice; on the morrow also the remainder of it shall be eaten;

17and the remainder of the flesh of the sacrifice on the third day shall be burned with fire.

18And if [any] of the flesh of the sacrifice of his peace-offering be eaten at all on the third day, it shall not be accepted, it shall not be reckoned to him that hath presented it; it shall be an unclean thing, and the soul that eateth of it shall bear his iniquity.

19And the flesh that toucheth anything unclean shall not be eaten; it shall be burned with fire. And as to the flesh, all that are clean may eat [the] flesh.

20But the soul that eateth the flesh of the sacrifice of peace-offering which is for Jehovah, having his uncleanness upon him, that soul shall be cut off from his peoples.

21And if any one touch anything unclean, the uncleanness of man, or unclean beast, or any unclean abomination, and eat of the flesh of the sacrifice of peace-offering, which is for Jehovah, that soul shall be cut off from his peoples.
