Revelation 6:7-8

When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, “Come.” I looked, and behold, an ashen horse; and he who sat 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.
