Revelation 9:1

“And the fifth angel sounded, etc.] His trumpet: and I saw a star fall from heaven unto the earth: some take this star to be Jesus Christ, the bright and morning star; and understand by falling, no other than his descending from heaven to earth, in which sense the word is used in (<011410>Genesis 14:10); and that because he is not only said to have the keys of hell and death, (<660118>Revelation 1:18); but particularly the key of the bottomless pit, (<662001>Revelation 20:1); but then there is a wide difference in the use of the key by the star here, and the angel there, or between the opening of the pit, and letting out smoke and locusts, and the shutting it up, and Satan in it; the one well…”

“THE FIFTH TRUMPET: THE FALLEN STAR OPENS THE ABYSS WHENCE ISSUE LOCUSTS. THE SIXTH TRUMPET. FOUR ANGELS AT THE EUPHRATES LOOSED. (Rev. 9:1-21) The last three trumpets of the seven are called, from Rev 8:13, the woe-trumpets. fall--rather as Greek, "fallen." When John saw it, it was not in the act of falling, but had fallen already. This is a connecting link of this fifth trumpet with Rev 12:8-9, Rev 12:12, "Woe to the inhabiters of the earth, for the devil is come down," &c. Compare Isa 14:12, "How art thou fallen from heaven, Lucifer, son of the morning!" the bottomless pit--Greek, "the pit of the abyss"; the orifice of the hell where Satan and his demons dwell.”

“And the fifth angel sounded - See the notes on Revelation 8:6-7. And I saw a star fall from heaven unto the earth - This denotes, as was shown in the notes on Revelation 8:10, a leader, a military chieftain, a warrior. In the fulfillment of this, as in the former case, we look for the appearance of some mighty prince and warrior, to whom is given power, as it were, to open the bottomless pit, and to summon forth its legions. That some such agent is denoted by the star is further apparent from the fact that it is immediately added, that “to him (the star) was given the key of the bottomless pit.” It could not be meant that a key would be given to a literal star, and we naturally suppose,…”

“And the fifth angel sounded, and I saw a star - Far different from that mentioned, Rev 8:11. This star belongs to the invisible world. The third woe is occasioned by the dragon cast out of heaven; the second takes place at the loosing of the four angels who were bound in the Euphrates. The first is here brought by the angel of the abyss, which is opened by this star, or holy angel. Falling to the earth - Coming swiftly and with great force. And to him was given - when he was come. The key of the bottomless pit - A deep and hideous prison; but different from "the lake of fire." Revelation 9:2”

“9:1-21 The fifth and sixth trumpets demonstrate how God’s judgment affects the people of the world and detail how futile it is to resist God. While these judgments should lead to repentance, they do not. Sin has such control over people that they choose to worship the evil forces that torture and murder them rather than repent and turn to God. 9:1-12 The fifth . . . trumpet, the first of the three terrors (8:13), brings the judgment of locusts from the bottomless pit, a place of horror. Ancient cultures viewed the oceanic depths, or the “abyss,” as a dwelling place of demonic forces (see study note on Gen 1:2).”

“the fifth: Rev 9:12, Rev 9:13, Rev 8:6-8, Rev 8:10, Rev 8:12, Rev 11:14, Rev 11:15 a star: Rev 1:20, Rev 8:10; Isa 14:12; Luk 10:18; Th2 2:3-8; Ti2 3:1-5 to him: Rev 1:18, Rev 20:1 the bottomless: Rev 9:2, Rev 9:11, Rev 17:8, Rev 20:10; Luk 8:31; Rom 10:7 \*Gr. Revelation 9:2”
