Revelation 6:9-11

21st Century King James Version

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 avenge our blood on them that dwell on the earth?”

¹¹ And white robes were given unto every one of them, and it was said unto them that they should rest yet for a little season, until their fellow servants and also their brethren, who were to be killed as they were, should be fulfilled.
