'Trumpet' in the Bible

I was in the Spirit on the Lord's Day when I heard behind me a loud voice like a trumpet,

After these things I looked, and there was a door standing open in heaven! And the first voice I had heard speaking to me like a trumpet said: "Come up here so that I can show you what must happen after these things."

The first angel blew his trumpet, and there was hail and fire mixed with blood, and it was thrown at the earth so that a third of the earth was burned up, a third of the trees were burned up, and all the green grass was burned up.

Then the second angel blew his trumpet, and something like a great mountain of burning fire was thrown into the sea. A third of the sea became blood,

Then the third angel blew his trumpet, and a huge star burning like a torch fell from the sky; it landed on a third of the rivers and on the springs of water.

Then the fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of them were darkened. And there was no light for a third of the day and for a third of the night likewise.

Then the fifth angel blew his trumpet, and I saw a star that had fallen from the sky to the earth, and he was given the key to the shaft of the abyss.

Then the sixth angel blew his trumpet, and I heard a single voice coming from the horns on the golden altar that is before God,

saying to the sixth angel, the one holding the trumpet, "Set free the four angels who are bound at the great river Euphrates!"

But in the days when the seventh angel is about to blow his trumpet, the mystery of God is completed, just as he has proclaimed to his servants the prophets."

Then the seventh angel blew his trumpet, and there were loud voices in heaven saying: "The kingdom of the world has become the kingdom of our Lord and of his Christ, and he will reign for ever and ever."
