Revelation 6:8-10

21st Century King James Version

⁸ And I looked, and behold, a pale horse, and his name that sat on him was Death, and Hell followed with him. And power was given unto them over a fourth part of the earth to kill with sword, and with hunger, and with death, and with the beasts of the earth.

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?”
