Matthew 19:3 Some Pharisees came to (Jesus) to test him. They asked, "Is it lawful for a man to divorce his wife for any and every reason?"
4 "Haven't you read," he replied, (quotes Genesis) "that at the beginning the Creator 'made them male and female,’ 5 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'? 6 So they are no longer two, but one. Therefore what God has joined together, let man not separate."
