Revelation 9:11

They have over them as king the angel of the abyss: his name in Hebrew is Abaddon, and in the Greek tongue he hath the name Apollyon.

A king, the angel of the abyss ... Who is this, if not Satan? Bruce identified this character, somewhat reluctantly, with "the fallen star of Revelation 9:1."[44] Caird also did the same thing,[45] but neither of them recognized him as Satan. Here he is given two names, "both of which mean the Destroyer;[46] and can this be some other than the devil? We do not think so.

Apollyon ... "Both Caligula and Nero aped the pagan God Apollo,[47] and Beckwith thought the use of this name was "a direct allusion to such a pretending Roman emperor."[48] If so, it is the same as saying that this Roman emperor Apollo was one and the same as the devil. Plummer identified this king over the locusts as "Satan," adding that, "the height of absurdity is reached by those writers who see in the name Apollyon a reference to Napoleon!"[49]
