Deuteronomy 23:22-24

English Standard Version

²² But if you refrain from vowing, you will not be guilty of sin. ²³ You shall be careful to do what has passed your lips, for you have voluntarily vowed to the Lord your God what you have promised with your mouth.

²⁴ “If you go into your neighbor's vineyard, you may eat your fill of grapes, as many as you wish, but you shall not put any in your bag.
