At the opening of the seventh seal,
Revelation 8:1 And when he openeth the seventh seal, there came silence in the heaven about half-an-hour,
seven angels had seven trumpets given them.
Revelation 8:2 and I saw the seven messengers who before God have stood, and there were given to them seven trumpets,
Another angel putteth incense to the prayers of the saints on the golden altar.
Revelation 8:3 and another messenger did come, and he stood at the altar, having a golden censer, and there was given to him much perfume, that he may give [it] to the prayers of all the saints upon the golden altar that [is] before the throne, Revelation 8:4 and go up did the smoke of the perfumes to the prayers of the saints out of the hand of the messenger, before God; Revelation 8:5 and the messenger took the censer, and did fill it out of the fire of the altar, and did cast [it] to the earth, and there came voices, and thunders, and lightnings, and an earthquake.
Four of the seven angels sound their trumpets, and great plagues follow.
Revelation 8:6 And the seven messengers who are having the seven trumpets did prepare themselves that they may sound; Revelation 8:7 and the first messenger did sound, and there came hail and fire, mingled with blood, and it was cast to the land, and the third of the trees was burnt up, and all the green grass was burnt up. Revelation 8:8 And the second messenger did sound, and as it were a great mountain with fire burning was cast into the sea, and the third of the sea became blood, Revelation 8:9 and die did the third of the creatures that [are] in the sea, those having life, and the third of the ships were destroyed. Revelation 8:10 And the third messenger did sound, and there fell out of the heaven a great star, burning as a lamp, and it did fall upon the third of the rivers, and upon the fountains of waters, Revelation 8:11 and the name of the star is called Wormwood, and the third of the waters doth become wormwood, and many of the men did die of the waters, because they were made bitter. Revelation 8:12 And the fourth messenger did sound, and smitten was the third of the sun, and the third of the moon, and the third of the stars, that darkened may be the third of them, and that the day may not shinethe third of it, and the night in like manner. Revelation 8:13 And I saw, and I heard one messenger, flying in the mid-heaven, saying with a great voice, 'Woe, woe, woe, to those dwelling upon the land from the rest of the voices of the trumpet of the three messengers who are about to sound.'
