Revelation 6:7-8 - The Fourth Seal
7 And when he had opened the fourth seal, I heard the voice of the fourth living being say, Come and see. 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 to them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
