Leviticus 19:7-9

Amplified Bible

⁷ But if it is eaten at all on the third day, it is repulsive; it will not be accepted [by God as an offering]. ⁸ Everyone who eats it will bear [the responsibility for] his wickedness, for he has profaned a holy thing of the Lord; and that person shall be cut off from his people [excluding him from the atonement made for them].

Various Laws

⁹ ‘Now when you reap the harvest of your land, you shall not reap to the very corners of your field, nor shall you gather the gleanings (grain left after reaping) of your harvest.
