Revelation 8:12-13 - The Fourth Trumpet
12 And the fourth angel sounded the trumpet, and the third of the sun was stricken, and a third of the moon, and a third of the stars; that a third of them might be darkened, and the day shone not, a third of it, and the night likewise.
13 And I saw, and heard one angel flying in the midst of heaven, saying with a great voice, Woe, woe, woe, to them dwelling upon earth from the rest of the voices of the trumpet of the three angels, about to sound the trumpet!
