Deuteronomy 23:17-23

17 There shall not be a harlot of the daughters of Israel, and there shall not be a fornicator of the sons of Israel; there shall not be an idolatress of the daughters of Israel, and there shall not be an initiated person of the sons of Israel.
18 Thou shalt not bring the hire of a harlot, nor the price of a dog into the house of the Lord thy God, for any vow; because even both are an abomination to the Lord thy God.
19 Thou shalt not lend to thy brother on usury of silver, or usury of meat, or usury of any thing which thou mayest lend out.
20 Thou mayest lend on usury to a stranger, but to thy brother thou shalt not lend on usury; that the Lord thy God may bless thee in all thy works upon the land, into which thou art entering to inherit it.
21 And if thou wilt vow a vow to the Lord thy God, thou shalt not delay to pay it; for the Lord thy God will surely require it of thee, and it shall be sin in thee.
22 But if thou shouldest be unwilling to vow, it is not sin in thee.
23 Thou shalt observe the words that proceed from between thy lips; and as thou hast vowed a gift to the Lord God, shalt thou do that which thou hast spoken with thy mouth.
