Revelation 8:2-6

2And I saw the seven angels who stand before God, and seven trumpets were given to them. 3Another angel, who had a golden censer, came and stood at the altar. He was given much incense to offer, with the prayers of all God’s people, on the golden altar in front of the throne. 4The smoke of the incense, together with the prayers of God’s people, went up before God from the angel’s hand.

5Then the angel took the censer, filled it with fire from the altar, and hurled it on the earth; and there came peals of thunder, rumblings, flashes of lightning and an earthquake.

The Trumpets 6Then the seven angels who had the seven trumpets prepared to sound them.
