“When he opened the sixth seal, I looked, and there came a great earthquake; the sun became black as sackcloth, the full moon became like blood, and the stars of the sky fell to the earth as the fig tree drops its winter fruit when shaken by a gale.  The sky vanished like a scroll rolling itself up, and every mountain and island was removed from its place.  Then the kings of the kings of the earth and the magnates and the generals and the rich and the powerful, and everyone, slave and free, hid in the caves and among the rocks of the mountains, calling to the mountains the rocks, ‘Fall on us and hide us from the face of the one seated on the throne and from the wrath of the Lamb; for the great day of their wrath has come, and who is able to stand?’” 

 Revelation 6:12-17
