18. You shall not bring the hire of a prostitute, or the wages of a male prostitute, into the house of the Lord your God for any vow; for both of these are an abomination to the Lord your God.
19. You shall not lend on interest to your brother; interest of money, interest of food, interest of anything that is lent on interest.
20. You may lend on interest to a foreigner; but to your brother you shall not lend on interest, that the Lord your God may bless you in all that you put your hand to, in the land where you go in to possess it.
21. When you vow a vow to the Lord your God, you shall not be slack to pay it; for the Lord your God will surely require it of you; and it would be sin in you.
22. But if you refrain from making a vow, it shall be no sin in you.
23. You shall observe and do that which has gone out of your lips. Whatever you have vowed to the Lord your God as a freewill offering, which you have promised with your mouth, you must do.
