Deuteronomy 24:19-21

KJ2000(i) 19 When you reap your harvest in your field, and have forgotten a sheaf in the field, you shall not go again to get 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.
