Deuteronomy 23:19-21

New Life Version

¹⁹ Do not make your brothers pay you for the use of money, food, or anything you might give them to use. ²⁰ You may make a stranger pay you for the use of money, but not your brother. So the Lord your God may bring good to you in all you do in the land you are going into to have for your own.

²¹ “When you make a promise to the Lord your God, do not be slow to pay it. It would be sin in you, for the Lord your God will be sure to ask you for it.
