Numbers 30:3

If a woman also... — Four distinct cases are contemplated in the following verses in regard to vows taken by women: — (1) that of an unmarried woman, living, in her youth, in the house of her father; (2) that of a woman who is unmarried at the time of making a vow, but enters into the state of marriage before the vow is fulfilled; (3) that of a widow, or of a divorced woman; and (4) that of a married woman. The sanctity and obligations of the fifth commandment are distinctly recognised and enforced in these verses. (See Matthew 15:4.) Whenever the vow which the young daughter had made should come to the ears of her father, he had the power either to ratify or to disannul it. If he remained silent the vow was ratified; if he disallowed the vow, the obligation to fulfil it no longer remained in force.
