19 When you cut down your harvest in your field, and have forgot a sheaf in the field, you shall not go again to fetch it: it shall be for the stranger, for the fatherless, and for the widow: that the LORD your God may bless you in all the work of your hands.

20 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.

21 When you gather the grapes of your vineyard, you shall not glean it afterward: it shall be for the stranger, for the fatherless, and for the widow.
