Deuteronomy 23:18-20

Modern English Version

¹⁸ You must never bring the wage of a prostitute or the wage of a dog into the house of the Lord your God for any vow, for both of these are abominations to the Lord your God.

¹⁹ You must not charge interest on a loan to your brother: interest on money, interest on food, or on anything that may be lent with interest. ²⁰ You may charge interest to a foreigner, but to your brother you may not lend with interest so 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.
