Deuteronomy 23:18-20

New Revised Standard Version Catholic Edition

¹⁸ You shall not bring the fee of a prostitute or the wages of a male prostitute^[a] into the house of the Lord your God in payment for any vow, for both of these are abhorrent to the Lord your God.

¹⁹ You shall not charge interest on loans to another Israelite, interest on money, interest on provisions, interest on anything that is lent. ²⁰ On loans to a foreigner you may charge interest, but on loans to another Israelite you may not charge interest, so that the Lord your God may bless you in all your undertakings in the land that you are about to enter and possess.
