New International Version 1984 (NIV1984)
4 “Haven’t you read,” he replied, “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.”
