Revelation 6:11-13 Common English Bible (CEB)
11 Each of them was given a white robe, and they were told to rest a little longer, until their fellow servants and brothers and sisters—who were about to be killed as they were—were finished.
12 I looked on as he opened the sixth seal, and there was a great earthquake. The sun became black as funeral clothing, and the entire moon turned red as blood. 13 The stars of the sky fell to the earth as a fig tree drops its fruit when shaken by a strong wind.
