Matthew 19:5-7

King James Version

⁵ And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?

⁶ Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.

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