This will be my last comment on this subject! I must make a correction to my statement about the names of only 2 angels. There is also the angel Abaddon/Apollyon, of the abyss, given at Rev 9:11. I also found an unnamed angel of Satan, mentioned by Paul. ( 2 Co 12:7 ) Abaddon is also mentioned 6 times in the Hebrew scriptures (OT) associated with the grave, death, fire that consumes, Job 26:6, 28:22, 31:12. (3) Ps 88:11 (1) Pr 15:11, 27:20 (2) One of Strong’s definition for this word is: Abaddon = “destruction” ( 4. the name of the angel-prince of the infernal regions, the minister of death and the author of havoc on the earth. ) You will notice in Rev 9:11 it mentions a “king” over the locusts which come out of the abyss. He is also the one who is given the “key” to the abyss. I’ll let you figure out/determine who he is.
