'Trumpet' in the Bible

I was in the Spirit [in special communication with the Holy Spirit and empowered to receive and record the revelation from Jesus Christ] on the Lord’s Day, and I heard behind me a loud voice like the sound of a trumpet,

After this I looked, and behold, a door standing open in heaven! And the first voice which I had heard, like the sound of a [war] trumpet speaking with me, said, “Come up here, and I will show you what must take place after these things.”

The first [angel] sounded [his trumpet], and there was [a storm of] hail and fire, mixed with blood, and it was hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up.

The second angel sounded [his trumpet], and something like a great mountain blazing with fire was hurled into the sea; and a third of the sea was turned to blood;

The third angel sounded [his trumpet], and a great star fell from heaven, burning like a torch [flashing across the sky], and it fell on a third of the rivers and on the springs of [fresh] waters.

Then the fourth angel sounded [his trumpet], and a third of the sun and a third of the moon and a third of the stars were struck, so that a third of them would be darkened and a third of the daylight would not shine, and the night in the same way [would not shine].

Then I looked, and I heard a solitary eagle flying in midheaven [for all to see], saying with a loud voice, “Woe, woe, woe [great wrath is coming] to those who dwell on the earth, because of the remaining blasts of the trumpets which the three angels are about to sound [announcing ever greater judgments]!”

Then the fifth angel sounded [his trumpet], and I saw a star (angelic being) that had fallen from heaven to the earth; and the key of the bottomless pit (abyss) was given to him (the star-angel).

Then the sixth angel sounded [his trumpet], and I heard a solitary voice from the four horns of the golden altar which stands before God,

saying to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.”

but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets.

Then the seventh angel sounded [his trumpet]; and there were loud voices in heaven, saying,“The kingdom (dominion, rule) of the world has become the kingdom of our Lord and of His Christ; and He will reign forever and ever.”
