Revelation 6
12 I looked when He broke the sixth seal, and there was a great earthquake; and the sun became black as sackcloth made of hair, and the whole moon became like blood;
13 and the stars of the sky fell to the earth, as a fig tree casts its unripe figs when shaken by a great wind.
14 The sky was split apart like a scroll when it is rolled up, and every mountain and island were moved out of their places.
15 Then the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains;
16 and they *said to the mountains and to the rocks, "Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb;
17 for the great day of their wrath has come, and who is able to stand?"
Revelation 7

2 And I saw another angel ascending from the rising of the sun, having the seal of the living God; and he cried out with a loud voice to the four angels to whom it was granted to harm the earth and the sea,
3 saying, "Do not harm the earth or the sea or the trees until we have sealed the bond-servants of our God on their foreheads."
4 And I heard the number of those who were sealed, one hundred and forty-four thousand sealed from every tribe of the sons of Israel:
5 from the tribe of Judah, twelve thousand were sealed, from the tribe of Reuben twelve thousand, from the tribe of Gad twelve thousand,
