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 on 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 allowed 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. 6 During those days people will seek death but will not find it; they will long to die, but death will elude them.
Revelation 7
144,000 Sealed
1 After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree. 2 Then I saw another angel coming up from the east, having the seal of the living God. He called out in a loud voice to the four angels who had been given power to harm the land and the sea: 3 “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.” 4 Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel.
IMO, the only believers alive at the time of the sounding of the fifth trumpet will be those with the seal of God in their foreheads (the 144,000). The rest of humanity will be inflicted with the fifth trumpet plague. If there were any other believers alive at that time, they would also be affected by this plague.
