Leviticus 19:3-7

Ye shall fear every man his mother, and his father, and keep my sabbaths: I am the LORD your God.

Turn ye not unto idols, nor make to yourselves molten gods: I am the LORD your God.

And if ye offer a sacrifice of peace offerings unto the LORD, ye shall offer it at your own will.

It shall be eaten the same day ye offer it, and on the morrow: and if ought remain until the third day, it shall be burnt in the fire.

And if it be eaten at all on the third day, it is abominable; it shall not be accepted.
