Numbers 30:7-9

Douay-Rheims 1899 American Edition

⁷ If she have a husband, and shall vow any thing, and the word once going out of her mouth shall bind her soul by an oath:

⁸ The day that her husband shall hear it, and not gainsay it, she shall be bound to the vow, and shall give whatsoever she promised.

⁹ But if as soon as he heareth he gainsay it, and make her promises and the words wherewith she had bound her soul of no effect: the Lord will forgive her.
