Revelation 6:10-12

Complete Jewish Bible

¹⁰ They cried out in a loud voice, “Sovereign Ruler, HaKadosh, the True One, how long will it be before you judge the people living on earth and avenge our blood?” ¹¹ Each of them was given a white robe; and they were told to wait a little longer, until the full number of their fellow-servants should be reached, of their brothers who would be killed, just as they had been.

¹² Then I watched as he broke the sixth seal, and there was a great earthquake, the sun turned black as sackcloth worn in mourning, and the full moon became blood-red.
