Matthew 19:7-9

Young's Literal Translation

⁷ They say to him, `Why then did Moses command to give a roll of divorce, and to put her away?'

⁸ He saith to them -- `Moses for your stiffness of heart did suffer you to put away your wives, but from the beginning it hath not been so.

⁹ `And I say to you, that, whoever may put away his wife, if not for whoredom, and may marry another, doth commit adultery; and he who did marry her that hath been put away, doth commit adultery.'
