Deuteronomy 24:20-22

Amplified Bible

²⁰ When you beat [the olives off of] your olive tree, do not search through the branches again; [whatever is left] shall be for the stranger, for the orphan, and for the widow.

²¹ “When you gather the grapes of your vineyard, you shall not glean it afterward; it shall be for the stranger, for the orphan, and for the widow. ²² You shall [thoughtfully] remember [the fact] that you were a slave in the land of Egypt; therefore I am commanding you to do this thing.
