Matthew 19:9 ASV

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

⁸  He saith unto them, Moses for your hardness of heart suffered you to put away your wives: but from the beginning it hath not been so.

⁹  And I say unto you, Whosoever shall put away his wife, except for fornication, and shall marry another, committeth adultery: and he that marrieth her when she is put away committeth adultery.

¹⁰  The disciples say unto him, If the case of the man is so with his wife, it is not expedient to marry.

¹¹  But he said unto them, Not all men can receive this saying, but they to whom it is given.
