'Trumpet' in the Bible
Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most certainly I tell you, they have received their reward.
He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.
For if the trumpet gave an uncertain sound, who would prepare himself for war?
in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we will be changed.
For the Lord himself will descend from heaven with a shout, with the voice of the archangel, and with God's trumpet. The dead in Christ will rise first,
the sound of a trumpet, and the voice of words; which those who heard it begged that not one more word should be spoken to them,
I was in the Spirit on the Lord's day, and I heard behind me a loud voice, like a trumpet
After these things I looked and saw a door opened in heaven, and the first voice that I heard, like a trumpet speaking with me, was one saying, "Come up here, and I will show you the things which must happen after this."
saying to the sixth angel who had one trumpet, "Free the four angels who are bound at the great river Euphrates!"
