'Pledges' in the Bible

If her father forbids her on the day he hears [of it], all her vows or her pledges that she bound on herself will not stand, and Yahweh will forgive her because her father has forgiven her.

But if her husband is completely silent from day to day, then he confirms all her vows or all her pledges that [are] on her; he confirms them because he was silent to her on the day he heard [them].
