Revelation 6:11-13 Evangelical Heritage Version (EHV)
11 A white robe was given to each one of them. And they were told to rest a little longer until their number would be complete, when their fellow servants and their brothers[a] would be put to death as they were.
The Sixth Seal: The Last Judgment
12 And I watched when the Lamb opened the sixth seal. There was a great earthquake. The sun became as black as sackcloth made of hair. The entire moon became like blood. 13 The stars of the sky fell to the earth as a fig tree drops its unripe figs when it is shaken by a strong wind.
