Philip Schaff

“ For as it is impossible for a soldier to contradict his general, and impossible for the generals themselves to disobey the king—for if any one oppose those set over him, he is altogether deserving of punishment—so it is impossible for the demons not to serve the angels who are their generals; and when they are adjured by them, they yield trembling, well knowing that if they disobey they shall be fully punished. But the angels also themselves, being adjured by the magicians in the name of their ruler, obey, lest, being found guilty of disobedience, they be destroyed. ”
