Divorce. Under the Mosaic Law a man could divorce his wife, but she could not divorce him. He was required to give her a written certificate of divorce. (De 24:1-4) Jesus Christ showed that such an arrangement for divorce in Israel was made as a concession out of regard for their hardheartedness. (Mt 19:8) If, however, a man had seduced a virgin girl who was not engaged, she was to become his wife (unless her father refused to give her to him), and he was not allowed to divorce her all his days.​—De 22:28, 29.

under the Law, polygamy and concubinage were practiced by allowance from Jehovah
