19 When you reap your harvest in your field, and have forgot a sheaf in the field, you shall not go again to get it: it shall be for the foreigner, for the fatherless, and for the widow; that Yahweh 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 foreigner, for the fatherless, and for the widow. 21 When you gather the grapes of your vineyard, you shall not glean it after yourselves: it shall be for the foreigner, for the fatherless, and for the widow.
