Revelation 6:11-13 World English Bible (WEB)
11 A long white robe was given to each of them. They were told that they should rest yet for a while, until their fellow servants and their brothers,[a] who would also be killed even as they were, should complete their course.
12 I saw when he opened the sixth seal, and there was a great earthquake. The sun became black as sackcloth made of hair, and the whole moon became as blood. 13 The stars of the sky fell to the earth, like a fig tree dropping its unripe figs when it is shaken by a great wind.
