Revelation 6:7-9

New Century Version

⁷ When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” ⁸ I looked, and there before me was a pale horse. Its rider was named death, and Hades^[a] was following close behind him. They were given power over a fourth of the earth to kill people by war, by starvation, by disease, and by the wild animals of the earth.

⁹ When the Lamb opened the fifth seal, I saw under the altar the souls of those who had been killed because they were faithful to the word of God and to the message they had received.
