Revelation 8:12-13 - The Fourth Trumpet
12 And, the fourth messenger, sounded; and the third of the sun was smitten, and the third of the moon, and the third of the stars, - in order that the third of them might be darkened, and the day might not shine for the third of it, and the night, in like manner.
13 And I saw, and I heard one eagle, flying in mid-heaven, saying with a loud voice - Woe! woe! woe! unto them that are dwelling upon the earth, by reason of the remaining voices of the trumpet, of the three messengers who are about to sound.
