Matthew 19:9-11

King James Version

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.

¹¹ But he said unto them, All men cannot receive this saying, save they to whom it is given.
