Rev 6:9-11

Revelation 6:9-11 ⁹ And when He opened the fifth seal, I saw underneath the altar the souls of them that were slain for the word of God, and for the testimony which they held. ¹⁰ And they cried out with a loud voice, saying, "How long, O Lord, holy and true, do You not judge and avenge our blood on them that dwell on the earth?" ¹¹ And a long white robe was given to them, and it was said to them that they should rest yet a while, until also their fellow servants and their brothers, who were about to be killed as also they were, should complete their course.
