Introduction to the Law of Vows
1
And Moses spake unto the heads of the tribes of the children of Israel, saying, This is the thing which Jehovah hath commanded.
2
When a man voweth a vow unto Jehovah, or sweareth an oath to bind his soul with a bond, he shall not break his word; he shall do according to all that proceedeth out of his mouth.
