Leviticus 19:7-9

The Voice

⁷ If any of it is eaten on the third day, your offering will not be accepted; by then it has become foul. ⁸ Anyone who consumes the peace offering on the third day will bear his guilt and suffer the consequences, for he has desecrated what has been set apart for Me. That person must be cut off from his people.

⁹ When you harvest the crops of your land, do not gather the grain all the way to the edges of your fields or pick up what was overlooked during the first round of harvesting.
