Deuteronomy 23 [20.] You may lend on interest to a foreigner; but to your brother you shall not lend on interest, that Yahweh your God may bless you in all that you put your hand to, in the land where you go in to possess it. When you vow a vow to Yahweh your God, you shall not be slack to pay it; for Yahweh your God will surely require it of you; and it would be sin in you. But if you refrain from making a vow, it shall be no sin in you. You shall observe and do that which has gone out of your lips. Whatever you have vowed to Yahweh your God as a freewill offering, which you have promised with your mouth, you must do. When you come into your neighbor’s vineyard, then you may eat of grapes your fill at your own pleasure; but you shall not put any in your container.
Deuteronomy 23 [25.] When you come into your neighbor’s standing grain, then you may pluck the ears with your hand; but you shall not move a sickle to your neighbor’s standing grain.
