Revelation 6:9-17
9 When the Lamb broke the fifth seal, I saw underneath the altar the souls of those who had been slain because of the word of God, and because of the testimony which they had maintained;
10 and they cried out with a loud voice, saying, "How long *, O Lord, holy and true, will You refrain from judging and avenging our blood on those who dwell on the earth?"
11 And there was given to each of them a white robe; and they were told that they should rest for a little while longer, until the number of their fellow servants and their brethren who were to be killed even as they had been, would be completed also.
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?"
They'll be avenged but they'll be avenged more quickly if we don't hide ourselves from their suffering.
