Matthew 19:7-9

21st Century King James Version

⁷ They said unto Him, “Why did Moses then command to give a writing of divorcement and to put her away?”

⁸ He said 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 who is put away doth commit adultery.”
