Leviticus 19:6

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

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

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

6 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.

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

8 Therefore every one that eateth it shall bear his iniquity, because he hath profaned the hallowed thing of the LORD: and that soul shall be cut off from among his people.

9 And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleanings of thy harvest.
