Deuteronomy 23:19-20
Deuteronomy 23:19-20 NKJV
“You shall not charge interest to your brother—interest on money or food or anything that is lent out at interest. To a foreigner you may charge interest, but to your brother you shall not charge interest, 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.
