Deuteronomy 23:21-23

New International Reader's Version

²¹ Don’t put off giving to the Lord your God everything you promise him. He will certainly require it from you. And you will be guilty of committing a sin. ²² But if you don’t make a promise, you won’t be guilty. ²³ Make sure you do what you promised to do. With your own mouth you made the promise to the Lord your God. No one forced you to do it.
