Revelation 8:12-13 - The Fourth Trumpet
12 And at the sounding of the fourth angel, a third part of the sun, and of the moon, and of the stars was made dark, so that there was no light for a third part of the day and of the night.
13 And there came to my ears the cry of an eagle in flight in the middle of heaven, saying with a great voice, Trouble, trouble, trouble, to all on the earth, because of the other voices of the horns of the three angels, whose sounding is still to come.
