Matthew 19
6 Ref So that they are no more two, but one flesh. What therefore God hath joined together, let not man put asunder.
7 Ref They say unto him, Why then did Moses command to give a bill of divorcement, and to put `her' away?
8 Ref 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.
