Those chapters do not help you.
The beast ascends out of the bottomless pit to overcome and kill the saints. Christ has the keys of hell and death, which the bottomless pit symbolizes. Since Christ has the keys, He gives the angel the key to open the pit. Sounds like the end of the thousand years when Satan is loosed from Rev 20.
Revelation 11:7 (KJV) And when they shall have finished their testimony,
the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
Revelation 1:18 (KJV) I am he that liveth, and was dead; and, behold,
I am alive for evermore, Amen; and have the keys of hell and of death.
Reviewing Rev 9:4-5 when the pit is first opened the minions coming out are only allowed to torment those who do not have the seal of God.
Revelation 9:1 (KJV) And the fifth angel sounded, and
I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
Revelation 9:4-5 (KJV) And it was commanded them that
they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads. And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
Then in Rev 11 the beast that ascends out of the pit can only kill the witnesses AFTER they have finished their testimony. What happens after that, they are called up to heaven, and the seventh angel sounds. This is the bodily resurrection on the last day, because that is when Christ returns, and our body is raised and changed (see 1Cor 15:51-56).
Revelation 11:15 (KJV) And
the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become
the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
What else happens when the seven trumpets have sounded? There is not more time for time is no more.
Revelation 10:4-6 (KJV) And
when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not. And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven, And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein,
that there should be time no longer:
Revelation 10:7 (KJV) But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
