Deuteronomy 23:21-23

Tree of Life Version

²¹ To a foreigner you may charge interest, but to your brother you are not to charge interest, so that Adonai your God may bless you in every undertaking of your hand on the land you are going in to possess.

²² “When you make a vow to Adonai your God, you are not to delay to make good on it—for Adonai your God will certainly require it of you, and you would have sin on you. ²³ But if you refrain from making a vow, you would not have sin on you.
