Mark 5:6

(non occ.) Now the assembly of the devils had prepared itself to resist the Divine power. But when He was approaching Who had power over all things, they proclaim aloud His eminent virtue. Wherefore there follows, But when he saw Jesus afar off, he ran and worshipped him, saying, &c.

(ubi sup.) Who dwelt in the tombs, because they delighted in dead works, that is, in sins; who were ever raging night and day, because whether in prosperity or in adversity, they were never free from the service of malignant spirits: again, by the foulness of their works, they lay as it were in the tombs, in their lofty pride, they wandered over the mountains, by words of most hardened infidelity, they as it were cut themselves with stones. But he said, My name is Legion, because the Gentile people were enslaved to divers idolatrous forms of worship. Again, that the unclean spirits going out from man enter into swine, which they cast headlong into the sea, implies that now that the people of the Gentiles are freed from the empire of demons, they who have not chosen to believe in Christ, work sacrilegious rites in hidden places.

Here again the demoniac is the people of the Gentiles, in a most hopeless case, bound neither by the law of nature, nor of God, nor by human fear. Or they are choked in hell without any touch of mercy by the rushing on of an early death; which evils many persons thus avoid, for by the scourging of the fool, the wise is made more prudent.
