For so, too, formerly the holy women who were hoping in God used to adorn themselves, subjecting themselves to their own husbands.”—1 Pet. 3:1-5, NW.
... If the believer decides this is the case with his marriage he may separate, but since adultery or death is the only way a marriage is canceled in Jehovah’s sight the believer is not free to remarry, even if a legal divorce is obtained: “If she should actually depart, let her remain single or else make up again with her husband; and a husband should not leave his wife,” without being under similar restrictions.—1 Cor. 7:12, 13, 16, 15, 11; Matt. 19:9; Mark 10:11, 12; Rom. 7:2, 3, NW.
