Revelation 8:12-13 - The Fourth Trumpet
12 And the fourth angel sounded his trumpet: 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 should be darkened, and that the day should not appear for the third part of it, and the night the same.
13 And I saw, and I heard an eagle flying in mid-heaven, saying with a loud voice, Woe, woe, woe, to them that dwell upon the earth, for the remaining voices of the trumpet of the three angels who are about to sound.
