Matthew 19:4-9

“Haven’t you read the Scriptures?” Jesus replied. “They record that from the beginning ‘God made them male and female.’” And he said, “‘This explains why a man leaves his father and mother and is joined to his wife, and the two are united into one.’ Since they are no longer two but one, let no one split apart what God has joined together.” “Then why did Moses say in the law that a man could give his wife a written notice of divorce and send her away?” they asked. Jesus replied, “Moses permitted divorce only as a concession to your hard hearts, but it was not what God had originally intended. And I tell you this, whoever divorces his wife and marries someone else commits adultery—unless his wife has been unfaithful.”
