When a man takes an oath to the Lord, or gives an undertaking having the force of an oath, let him not go back from his word, but let him do whatever he has said he will do.

If a man vow a vow unto the LORD, or swear 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.
