Revelation 6:10-14

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 live on the earth?”

And a white robe was given to each of them; and they were told that they were to rest for a little while longer, until the number of their fellow servants and their brothers and sisters who were to be killed even as they had been, was completed also. The Sixth Seal: Terror

And I looked when He broke the sixth seal, and there was a great earthquake; and the sun became as black as sackcloth made of hair, and the whole moon became like blood;

and the stars of the sky fell to the earth, as a fig tree drops its unripe figs when shaken by a great wind.

The sky was split apart like a scroll when it is rolled up, and every mountain and island was removed from its place.
