Deuteronomy 24:20-22

Revised Standard Version

²⁰ When you beat your olive trees, you shall not go over the boughs again; it shall be for the sojourner, the fatherless, and the widow. ²¹ When you gather the grapes of your vineyard, you shall not glean it afterward; it shall be for the sojourner, the fatherless, and the widow. ²² You shall remember that you were a slave in the land of Egypt; therefore I command you to do this.
