Revelation 6:7-9

Common English Bible

⁷ When he opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” ⁸ So I looked, and there was a pale green horse. Its rider’s name was Death, and the Grave was following right behind. They were given authority over a fourth of the earth, to kill by sword, famine, disease, and the wild animals of the earth.

⁹ When he opened the fifth seal, I saw under the altar those who had been slaughtered on account of the word of God and the witness they had given.
