Matthew 19:4-8

“Haven’t you read,” He replied, “that He who created them in the beginning made them male and female,” and He also said: “For this reason a man will leave his father and mother and be joined 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, man must not separate.” “Why then,” they asked Him, “did Moses command us to give divorce papers and to send her away? ” He told them, “Moses permitted you to divorce your wives because of the hardness of your hearts. But it was not like that from the beginning.
