Matthew 5:31-32

“It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’ But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery. (Matthew 5:31-32)

Matthew 19:3-10

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? So 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.”

The disciples said to him, “If this is the situation between a husband and wife, it is better not to marry.”
