'Pledges' in the Bible

But if her father disapproves of her [making her vow] on the day that he hears about it, none of her vows or her pledges by which she has bound herself shall stand; and the Lord will forgive her because her father has disapproved of her [making the vow].

But if her husband says nothing to her [concerning the matter] from day to day, then he confirms all her vows or all her pledges which are on her. He has confirmed them because he said nothing to her on the day he heard them.
