Revelation 6:7 - 6:8
7 And when He opened the fourth seal, I heard the voice of the fourth living creature saying, “Come.” 8 Then I looked, and behold, a pale horse; and he who sits on it had the name Death, and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword and with famine and with pestilence and by the wild beasts of the earth.
