Revelation 6

The Fourth Seal: Death

7 And when the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, "Come!"

8 Then I looked and saw a pale green horse. Its rider’s name was Death, and Hades followed close behind. And they were given authority over a fourth of the earth, to kill by sword, by famine, by plague, and by the beasts of the earth.
