Matthew 19:8

He said to them, "Moses permitted you to divorce your wives, on account of the hardness of your hearts, but it was not so from the beginning.

But Jesus answered him, "Come now, this is how we should fulfil all our duty to God." Then John gave in to him.

so the daemons begged him saying, "If you are going to cast us out, send us into that drove of swine."

Jesus said to them, "He wrote you that command on account of the hardness of your hearts.

But what I have just said is by way of concession, not command.
