Primasius of Hadrumetum

Therefore the Apostle says that they are drawn away by the unrighteous deception of those who perish, because they did not receive the love of the truth for their salvation. "And for this cause God will send them a working of delusion, that they should believe a lie, that all may be condemned who did not believe the truth, but had pleasure in unrighteousness" (2 Thess 2:10-12).
Thus the character of his deeds corresponds to his name: destroyer. This is the meaning of the Hebrew Abaddon and the Greek Apollyon.
