Hi Duran🙂
Revelation 1:10
"By inspiration I came to be in the Lord’s day, and I heard behind me a strong voice like that of a trumpet..."
Revelation 4:1
"After this I saw, and look! an opened door in heaven, and the first voice that I heard speaking with me was like a trumpet..."
Christ's voice from heaven as the executioner of God's judgment is likened to a trumpet. After he is enthroned, he rides vigorously to execute God's judgments, depicted as plagues/thunders/bowls/trumpets.
The trumpet at Revelation 8:7 talks about hail. So do these other places in Revelation...
Revelation 11:19
"And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail."
Revelation 16:21
"Then great hailstones, each about the weight of a talent, fell from heaven on the people, and the people blasphemed God because of the plague of hail, for the plague was unusually great."
The trumpet at Revelation 8:8 talks about the sea turning into blood. So does Revelation 16:3 when talking about the second bowl...
"The second one poured out his bowl into the sea. And it became blood like that of a dead man, and every living creature died, yes, the things in the sea..."
It's the same idea with all the trumpets. They match other visions in Revelation. The locusts/charging cavalry goes along with the second horseman and the attack on Babylon the Great. Revelation 9:14 and the trumpet about the four angels at the Euphrates matches the four angels at Revelation 7:1,2, and all the other visions with the four living creatures like at Revelation 15:7. It's all the same thing just told in slightly different ways, going through the different parts of the 3 1/2 years of the great tribulation.
Revelation 11:19 says "And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail." Lightning, voice, thunders, earthquake, hail...it's the theme, the plagues, etc, repetition for emphasis.
Revelation 14:8 says Babylon has fallen, but then again in Revelation 16:19 it says "The great city split into three parts, and the cities of the nations fell; and Babylon the Great was remembered before God, to give her the cup of the wine of the fury of his wrath." It's the same thing from a different angle.
That the "seventh" trumpet is not really seventh from a linear point of view is shown in that the visions repeat again in chapters 12 and 13, recapping the 3 1/2 year timeline.
The trumpet Paul was talking about ("the last trumpet") was the one Jesus mentioned in Matthew 24:31...
"And he will send out his angels with a great trumpet sound, and they will gather his chosen ones together from the four winds, from one extremity of the heavens to their other extremity."
That is at the end of the 3 1/2 year great tribulation.
