Leviticus 7
15 Ref And 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.
16 Ref But 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:
17 Ref But if any of the flesh of the offering is still unused on the third day, it is to be burned with fire.
18 Ref And 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.
