Origen, on Jude 1:6

“And the angels who kept not their principality, but forsook their own habitation, he hath reserved under darkness in everlasting chains, unto the judgment of the great day.”

“Not only man, but also the "sons of God, seeing the daughters of men that they are fair, took for themselves wives of all whom they chose," and consistently all those who left "their own dwelling" and did not preserve their own principality - and by "principality" I mean not in reference to power but to the beginning and foundation; just as for man, the beginning was to be in paradise, but the end perhaps due to transgression in Hades below or some such place, so also for each of the fallen ones a particular beginning is given.”
