Revelation 8:12-13 - The Fourth Trumpet
12 And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars, so that the third part of them was darkened, and the day shone not for a third part of it, and the night in like manner.
13 And I saw, and heard an eagle flying in midheaven, saying with a loud voice, Woe, woe, woe, to those who dwell on the earth, by reason of the remaining voices of the trumpet of the three angels who are yet to sound!
