19And flesh touched by any unclean thing may not be taken for food: it is to be burned with fire; and as for the flesh of the peace-offerings, everyone who is clean may take it as food:
20But he who is unclean when he takes as food the flesh of the peace-offerings, which are the Lord's, will be cut off from his people.
21And anyone who, after touching any unclean thing of man or an unclean beast or any unclean and disgusting thing, takes as food the flesh of the peace-offerings, which are the Lord's, will be cut off from his people.
23Say to the children of Israel: You are not to take any fat, of ox or sheep or goat, for food.
24And the fat of that which comes to a natural death, and the fat of that which is attacked by beasts, may be used for other purposes, but not in any way for food.
25For anyone who takes as food the fat of any beast of which men make an offering by fire to the Lord, will be cut off from his people.
