You must not strip your vineyard bare or gather its fallen grapes. Leave them for the poor and the foreigner. I am the LORD your God.

Deuteronomy 24:19

Deuteronomy 24:21
When you gather the grapes of your vineyard, you must not go over the vines again. What remains will be for the foreigner, the fatherless, and the widow.

When you beat your olive tree, you shall not go over the boughs again: it shall be for the stranger, for the fatherless, and for the widow.
