Numbers 30:14-18

But if her husband altogether hold his peace at her from day to day; then he establisheth all her vows, or all her bonds, which are upon her: he confirmeth them, because he held his peace at her in the day that he heard them.

But if he shall any ways make them void after that he hath heard them; then he shall bear her iniquity.

These are the statutes, which the LORD commanded Moses, between a man and his wife, between the father and his daughter, being yet in her youth in her father’s house.
