Revelation 6:9-11

New International Version - UK

⁹ When he opened the fifth seal, I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. ¹⁰ They called out in a loud voice, ‘How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?’ ¹¹ Then 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, their brothers and sisters,^[a] were killed just as they had been.
