I can't remember how the WTBS interpretes Revelation 9 and the falling star but from what I recall it did not make sense (like anything did). here is my take:
Revelation 9 (New International Version)
New International Version (NIV)Revelation 9
1 The fifth angel sounded his trumpet, and I saw a star that had fallen from the sky to the earth. The star was given the key to the shaft of the Abyss. 2 When he opened the Abyss, smoke rose from it like the smoke from a gigantic furnace. The sun and sky were darkened by the smoke from the Abyss. 3 And out of the smoke locusts came down upon the earth and were given power like that of scorpions of the earth. 4 They were told not to harm the grass of the earth or any plant or tree, but only those people who did not have the seal of God on their foreheads. 5 They were not given power to kill them, but only to torture them for five months. And the agony they suffered was like that of the sting of a scorpion when it strikes a man. 6 During those days men will seek death, but will not find it; they will long to die, but death will elude them.
7 The locusts looked like horses prepared for battle. On their heads they wore something like crowns of gold, and their faces resembled human faces. 8 Their hair was like women's hair, and their teeth were like lions' teeth. 9 They had breastplates like breastplates of iron, and the sound of their wings was like the thundering of many horses and chariots rushing into battle. 10 They had tails and stings like scorpions, and in their tails they had power to torment people for five months. 11 They had as king over them the angel of the Abyss, whose name in Hebrew is Abaddon, and in Greek, Apollyon. [a]
The star indicates to me that this would be Satan and has been given the key to the abyss. I believe the abyss here is directly related to 2 Peter and Jude where it speaks of the the original fallen angels (noah) being imprisoned. The WTBS says tartarus is a "spiritual" imprisonment but everything I have seen in Greek commentaries says otherwise. The word denotes a physical bonding/imprisonment. So, if we reflect on what Jesus said about the last days being as the days of noah were, eating and drinking, etc. it involves more than a precursory look.
ENOCH 7:1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them . . . And they 3 became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed 4 all the acquisitions of men. And when men could no longer sustain them, the giants turned against 5 them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and 6 fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones. (The Apocrypha and Pseudepigrapha of the Old Testament, R.H. Charles)
Here the eating and drinking and marrying infer something far more sinister than just having a good 'ole time. I wonder if Jesus was hinting (along with the words used in Revelation, 2 Peter, and Jude) that in the last days Satan would be authorized to release the depraved fallen angels who would be permitted to torture humans but not kill them. This would fit with Job where Jehovah allowed Satan to torture Job but not to go as far as death. It is interesting that Revelation speaks of these captives as locusts with what appears to be crowns, lions teeth, long hair as a woman, wings, and stingers. Could this show how depraved these angels might be? Crowns in the sense that angels are allowed to be "gods" or rulers in this system as is indicated in Daniel where it speaks of the prince of Perisa and king of Greece. Lions teeth which refers to Peter saying that Satan the Devil is likened to a lion on the hunt for rightous humans. Womens hair, which is shown in the bible to be a sign of disrespect for a man (these locusts have mens faces) further showing there unholiness.
The demons in Jesus day also begged him not to send them to the abyss so I wonder if this is one and the same. Perhaps in the end these depraved demons will be allowed to do there thing in which Revelation says many will long for death but not find it or a way out.
Also, what I find interesting is that a Beast ascends out of this abyss. Why does the WTBS insist that this is the UN or some other government? It almost sounds like the fallen angels have been working on there own means of governing people. Just a thought on this last part. Any other thoughts? Thanks.
