Leviticus 19:3-10

³Every one of you shall reverence his mother and his father, and you shall keep My sabbaths; I am the Lord your God. ⁴Do not turn to idols or make for yourselves molten gods; I am the Lord your God.

⁵‘Now when you offer a sacrifice of peace offerings to the Lord, you shall offer it so that you may be accepted. ⁶It shall be eaten the same day you offer it, and the next day; but what remains until the third day shall be burned with fire. ⁷So if it is eaten at all on the third day, it is an offense; it will not be accepted. ⁸Everyone who eats it will bear his iniquity, for he has profaned the holy thing of the Lord; and that person shall be cut off from his people.

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 of your harvest. ¹⁰Nor shall you glean your vineyard, nor shall you gather the fallen fruit of your vineyard; you shall leave them for the needy and for the stranger. I am the Lord your God.
