'Vowest' in the Bible

Thou mayest not eat within thy gates the tithe of thy corn, or of thy wine, or of thy oil, or the firstlings of thy herds or of thy flock, nor any of thy vows which thou vowest, nor thy freewill offerings, or heave offering of thine hand:

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.
