“Tell the Israelites that these are the instructions to follow if a man's wife has an affair, being unfaithful to him
You must not commit adultery.
The Lord told Moses,
This is the rule to follow in cases of jealousy when a wife has an affair and makes herself unclean while married to her husband,
Should a man marry a woman, but then isn't pleased with her because he finds out something shameful about her, he is allowed to write out a certificate of divorce for her, give it to her, and send her out of his house.
