Revelation 6:9-11

Godbey(i) 9 And when he opened the fifth seal, I saw beneath the altar the souls of those who had been slain on account of the word of God, and the testimony which they had. 10 And they cried with a great voice, saying, How long, O Lord, holy and true, do you not judge and avenge our blood from those who dwell upon the earth? 11 And a white robe was given to each of them; and it was said to them, that they should wait a little while, until their fellow-servants and brethren, who are about to be slain as they were should be fulfilled.
