Revelation 6:9-11

Complete Jewish Bible

⁹ When the Lamb broke the fifth seal, I saw underneath the altar the souls of those who had been put to death for proclaiming the Word of God, that is, for bearing witness. 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.
