The Lord says, “If a man divorces his wife, and she leaves him and becomes another man's wife, he cannot take her back again. This would completely defile the land. But, Israel, you have had many lovers, and now you want to return to me!
Judah also saw that I divorced Israel and sent her away because she had turned from me and had become a prostitute. But Judah, Israel's unfaithful sister, was not afraid. She too became a prostitute
“As I passed by again, I saw that the time had come for you to fall in love. I covered your naked body with my coat and promised to love you. Yes, I made a marriage covenant with you, and you became mine.” This is what the Sovereign Lord says.
But now I tell you: if a man divorces his wife for any cause other than her unfaithfulness, then he is guilty of making her commit adultery if she marries again; and the man who marries her commits adultery also.
Now, it is actually being said that there is sexual immorality among you so terrible that not even the heathen would be guilty of it. I am told that a man is sleeping with his stepmother!
A married woman is not free as long as her husband lives; but if her husband dies, then she is free to be married to any man she wishes, but only if he is a Christian.
