21 `When thou vowest a vow to Jehovah thy God, thou dost not delay to complete it; for Jehovah thy God doth certainly require it from thee, and it hath been in thee -- sin
21
If you make a vow to the LORD your God, do not be slow to pay it, for the LORD your God will certainly demand it of you and you will be guilty of sin.
