Revelation 6:8-10

Douay-Rheims 1899 American Edition

⁹ And when he had opened the fifth seal, I saw under 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 with a loud voice, saying: How long, O Lord (holy and true) dost thou not judge and revenge our blood on them that dwell on the earth?
