JPS_ASV_Byz⁽ⁱ⁾ ⁹ And when he opened the fifth seal, I saw underneath the altar the souls of them that had been slain for the word of God, and for the testimony of the Lamb which they held: ¹⁰ and they cried with a great voice, saying, How long, O Master, the holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? ¹¹ And there was given them to each one a white robe, and it was said unto them, that they should rest yet for a time, until their fellow-servants and their brethren, and the ones that are about to be killed even as they also were, shall be fulfilled.
