'Vowest' in the Bible

Thou mayest not eat within thy gates the tithe of thy corn, or of thy new wine, or of thine oil, or the firstlings of thy kine or of thy sheep, nor any of thy vows which thou vowest, nor thy voluntary-offerings, nor the heave-offering of thy hand;

When thou vowest a vow to Jehovah thy God, thou shalt not delay to perform it; for Jehovah thy God will certainly require it of thee, and it shall be sin in thee.
