Matthew 19:8-10

King James Version

⁸ He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so.

⁹ And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.

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