Deuteronomy 23:22-24

Amplified Bible, Classic Edition

²² But if you refrain from vowing, it will not be sin in you.

²³ The vow which has passed your lips you shall be watchful to perform, a voluntary offering which you have made to the Lord your God, which you have promised with your mouth.

²⁴ When you come into your neighbor’s vineyard, you may eat your fill of grapes, as many as you please, but you shall not put any in your vessel.
