Revelation 6:7-8 - The Fourth Seal
7 When the Lamb broke the fourth seal I heard the voice of the fourth living creature say, "Come." 8 I looked and a pale-colored horse appeared. Its rider's name was Death, and Hades came close behind him; and authority was given to them over the fourth part of the earth, to kill with the sword or with famine or pestilence or by means of the wild beasts of the earth.
