Judges

And Jacob vowed a vow, saying, If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on,

And Israel vowed a vow unto the Lord, and said, If thou wilt indeed deliver this people into my hand, then I will utterly destroy their cities.

And she vowed a vow, and said, O Lord of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the Lord all the days of his life, and there shall no razor come upon his head.

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

Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.
