Revelation 6:10-12

Common English Bible

¹⁰ They cried out with a loud voice, “Holy and true Master, how long will you wait before you pass judgment? How long before you require justice for our blood, which was shed by those who live on earth?” 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.
