^20 [a]Do not charge your brother interest, whether it be on money or food or anything else that could earn interest. ²¹ You can charge a foreigner interest, but you cannot charge a brother interest. For this you will be blessed by the Lord, your God, in everything that you undertake in the land that you are entering to possess.

²² If you make a vow to the Lord, your God, do not be lax in paying it off, for the Lord, your God, will certainly require it of you, and you would be guilty of a sin.
