Matthew 19:8

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

But Jesus answered him, "Let it be so now; for thus it is fitting for us to fulfill all righteousness." Then he consented.

And the demons begged him, "If you cast us out, send us away into the herd of swine."

But Jesus said to them, "Because of your hardness of heart he wrote you this commandment.

I say this by way of concession, not of command.
