Sacred Promises to the Lord

Moses said:

^21 (A) People of Israel, if you make a sacred promise to give a gift to the Lord, then do it as soon as you can. If the Lord has to come looking for the gift you promised, you will be guilty of breaking that promise. ²² On the other hand, if you never make a sacred promise, you can't be guilty of breaking it. ²³ You must keep whatever promises you make to the Lord. After all, you are the one who chose to make the promises.

Promises

^33 (A) You know our ancestors were told, “Don't use the Lord's name to make a promise unless you are going to keep it.”
