12 I watched as he opened the sixth seal. There was a great earthquake.The sun turned black like sackcloth made of goat hair, the whole moon turned blood red, 13 and the stars in the sky fell to earth, as figs drop from a fig tree when shaken by a strong wind. 14 The heavens receded like a scroll being rolled up, and every mountain and island was removed from its place.
15 Then the kings of the earth, the princes, the generals, the rich, the mighty, and everyone else, both slave and free, hid in caves and among the rocks of the mountains. 16 They called to the mountains and the rocks, “Fall on us and hide us[f] from the face of him who sits on the throne and from the wrath of the Lamb! 17 For the great day of their[g]wrath has come, and who can withstand it?”
