Numbers 30:2-4

2If a man shall vow a vow to 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.1

3If a woman also shall vow a vow to the LORD, and bind herself by a bond, being in her father’s house in her youth; 4And her father shall hear her vow, and her bond by which she hath bound her soul, and her father shall hold his peace at her: then all her vows shall stand, and every bond by which she hath bound her soul shall stand.
