Matthew 19:6-10

So they are no longer two, but one flesh. Therefore, what God has joined together, no person is to separate.”

They *said to Him, “Why, then, did Moses command to give her a certificate of divorce and send her away?”

He *said to them, “Because of your hardness of heart Moses permitted you to divorce your wives; but from the beginning it has not been this way.

And I say to you, whoever divorces his wife, except for sexual immorality, and marries another woman commits adultery.”

The disciples *said to Him, “If the relationship of the man with his wife is like this, it is better not to marry.”
