If a man marries a woman who becomes displeasing to him because he finds something indecent about her, and he writes her a certificate of divorce, gives it to her and sends her from his house, and if after she leaves his house she becomes the wife of another man, and her second husband dislikes her and writes her a certificate of divorce, gives it to her and sends her from his house, or if he dies, then her first husband, who divorced her, is not allowed to marry her again after she has been defiled. That would be detestable in the eyes of the LORD. Do not bring sin upon the land the LORD your God is giving you as an inheritance. Deuteronomy 24:1-4
Divorce was permitted in the Israelite community, but not preferred by God.
Deuteronomy 24 is talking about what to do in that situation, but it does not tell a man to toss away his wife if she displeases him. God is upset that people capriciously fall in and out of love because of convenience.
In Deuteronomy 22, God told a man who accuses his wife of sexual misconduct and that accusation is found false, that the man can never divorce her. It protected women from false accusations. God also says that if a man rapes a woman, he must marry her and not divorce her. Again, it is not advocating rape, but giving rules to protect the women when that occurs.
Jesus spoke on divorce.
Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?”
“Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? They are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
“Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?”
Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.” Matthew 19:3-9
Moses allowed divorce because people stubbornly asked for it. Jesus said there are only a few cases when divorce is permittable. However, God never wanted divorce to happen.
