Numbers 30:6

Rather, And if she shall at all be an husband’s, and her vows shall be upon her, or a rash utterance of her lips, wherewith she hath bound her soul, etc. The “at all” intimates that the case of a girl betrothed but not yet actually married is here especially contemplated. After betrothal, a woman continued to reside, until the period of her marriage arrived, in her father’s house; but her property was from that time forward vested in her husband, and she was so far regarded as personally his, that an act of faithlessness to him was, like adultery, punishable with death Deuteronomy 22:23. Hence, his right to control her vows even before he actually took her home as his wife.
