Revelation 6:9-11

Twentieth_Century(i) 9 When the Lamb opened the fifth seal, I saw under the altar the souls of those who had been killed for the sake of God's Message and for the testimony which they had borne. 10 They cried in a loud voice--'How long, O Sovereign Lord, holy and true, before thou wilt give judgment and avenge our blood upon all who are living upon the earth?' 11 Then to each of them was given a white robe, and they were told to rest yet a little longer, till the number of their fellow-servants and of their Brothers who were about to be put to death, as they had been, should be complete.
