Leviticus 7:15-20

¹⁵And the flesh of the praise-offering is to be taken as food on the day when it is offered; no part of it may be kept till the morning.

¹⁶But if his offering is made because of an oath or given freely, it may be taken as food on the day when it is offered; and the rest may be used up on the day after:

¹⁷But if any of the flesh of the offering is still unused on the third day, it is to be burned with fire.

¹⁸And if any of the flesh of the peace-offering is taken as food on the third day, it will not be pleasing to God and will not be put to the account of him who gives it; it will be unclean and a cause of sin to him who takes it as food.

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.
