Leviticus 7:20-21

CLV(i) 20 Yet the soul who eats flesh from the sacrifice of peace offerings, which are to Yahweh, while his uncleanness is on him, that soul will be cut off from his kinsmen. 21 When a soul touches anything unclean, the uncleanness of a human or an unclean beast or any unclean swarmer, and eats any of the flesh of the sacrifice of peace offerings which are to Yahweh, then that soul will be cut off from his kinsmen.
