20. When you beat your olive trees, you shall not go over the boughs again; it shall be for the stranger, 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 stranger, the fatherless, and the widow.
22. And you shall remember that you were a slave in the land of Egypt; therefore I command you to do this thing.
