Deuteronomy 23:19-23

New King James Version

^19 (A)“You shall not charge interest to your brother—interest on money or food or anything that is lent out at interest. ^20 (B)To a foreigner you may charge interest, but to your brother you shall not charge interest, ^(C)that the Lord your God may bless you in all to which you set your hand in the land which you are entering to possess.

^21 (D)“When you make a vow to the Lord your God, you shall not delay to pay it; for the Lord your God will surely require it of you, and it would be sin to you. ²² But if you abstain from vowing, it shall not be sin to you. ^23 (E)That which has gone from your lips you shall keep and perform, for you voluntarily vowed to the Lord your God what you have promised with your mouth.
