'Vowest' in the Bible

Thou mayest not eat within thy gates the tithe of thy grain, or of thy new wine, or of thine oil, or the firstlings of thy herd or of thy flock, nor any of thy vows which thou vowest, nor thy freewill-offerings, nor the heave-offering of thy hand;

When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou vowest.
