Revelation 6:8

So I looked, and behold, an ashy pale horse [black and blue as if made so by bruising], and its rider's name was Death, and Hades (the realm of the dead) followed him closely. And they were given authority and power over a fourth part of the earth to kill with the sword and with famine and with plague (pestilence, disease) and with wild beasts of the earth. [Ezek. 5:12; Hos. 13:14.]
