Deuteronomy 23:23-25

New International Version

²³ Whatever your lips utter you must be sure to do, because you made your vow freely to the Lord your God with your own mouth.

²⁴ If you enter your neighbor’s vineyard, you may eat all the grapes you want, but do not put any in your basket. ²⁵ If you enter your neighbor’s grainfield, you may pick kernels with your hands, but you must not put a sickle to their standing grain.^(A)
