Revelation 6:9-11

Lamsa(i) 9 And when he had opened the fifth seal, I saw under the altar the souls of those who had been slain for the sake of the word of God and for the testimony of the Lamb which they had: 10 And they cried with a loud voice saying, How long, O LORD, holy and true, do you not judge and avenge our blood on those who dwell on the earth? 11 And a white robe was given to every one of them; and it was said to them, that they should rest yet for a little while, until the time should be fulfilled when their fellowservants and their brethren should be killed also as they had been.
