Not true.
Mar 10:3
And he answered and said unto them, What did Moses command you?
Jesus said unto them, What did Moses command you?
He did not say, What command can I formulate based upon a reality described in Genesis?
After God had made Eve from one of Adam's ribs, Moses said, Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. From Jesus' perspective, implicit in those words was the command for a man to not put asunder what God has joined together. I will stick with Jesus' understanding of this command from Moses, and you are free to do otherwise.
