'Undertakings' in the Bible

But if her father, hearing of it, makes her take back her word, then the oaths or the undertakings she has given will have no force; and she will have forgiveness from the Lord, because her oath was broken by her father.

If her husband, hearing of it, says nothing to her at the time, then the oaths she made and the undertakings she gave will have force.

But if the days go on, and her husband says nothing whatever to her, then he is giving the support of his authority to her oaths and undertakings, because at the time of hearing them he said nothing to her.
