Matthew 19:6-8

New American Standard Bible

Therefore, what God has joined together, no person is to separate.” ⁷ They *said to Him, “^(A)Why, then, did Moses command to give her a certificate of divorce and send her away?” ⁸ He *said to them, “Because of your hardness of heart Moses permitted you to ^[a]divorce your wives; but from the beginning it has not been this way.
