15 The meat of their fellowship offering of thanksgiving must be eaten on the day it is offered; they must leave none of it till morning.
16 “ ‘If, however, their offering is the result of a vow or is a freewill offering, the sacrifice shall be eaten on the day they offer it, but anything left over may be eaten on the next day.
17 Any meat of the sacrifice left over till the third day must be burned up.
18 If any meat of the fellowship offering is eaten on the third day, the one who offered it will not be accepted. It will not be reckoned to their credit, for it has become impure; the person who eats any of it will be held responsible.
19 “ ‘Meat that touches anything ceremonially unclean must not be eaten; it must be burned up. As for other meat, anyone ceremonially clean may eat it.
20 But if anyone who is unclean eats any meat of the fellowship offering belonging to the LORD, they must be cut off from their people.
21 Anyone who touches something unclean—whether human uncleanness or an unclean animal or any unclean creature that moves along the grounda —and then eats any of the meat of the fellowship offering belonging to the LORD must be cut off from their people.’ ”

Eating Fat and Blood Forbidden

22 The LORD said to Moses,
23 “Say to the Israelites: ‘Do not eat any of the fat of cattle, sheep or goats.
24 The fat of an animal found dead or torn by wild animals may be used for any other purpose, but you must not eat it.
25 Anyone who eats the fat of an animal from which a food offering may beb presented to the LORD must be cut off from their people.
