Numbers 30:1-2

Numbers 30:1-2 ASV

And Moses spake unto the heads of the tribes of the children of Israel, saying, This is the thing which Jehovah hath commanded. 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.
