Revelation 8:12-13 - The Fourth Trumpet
12 When the fourth angel blew his trumpet, one-third of the sun, one-third of the moon, and one-third of the stars were struck so that one-third of them turned dark. One-third of the day was kept from having light, as was the night.
13 Then I looked, and I heard an eagle flying overhead say in a loud voice, "How terrible, how terrible, how terrible for those living on the earth, because of the blasts of the remaining trumpets that the three angels are about to blow!"
