And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; And the stars of heaven fell unto the earth, even as a fig tree casts its unripe figs, when it is shaken by a mighty wind. And the heavens departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.

And the kings of the earth, and the great men, and the rich men, and the generals , and the mighty men, and every slave, and every free man, hid themselves in the dens and in the rocks of the mountains; And said to the mountains and rocks, Fall on us, and hide us from the face of him that sits on the throne, and from the wrath of the Lamb: For the great day of his wrath has come; and who shall be able to stand? (Revelation 6:12-17)
