Revelation 6:1-8  In this passage Jesus is the Lamb opening the seals in verses 1, 3, 5 and 7.  In verse 2 the Antichrist on the White Horse is given authority to conquer the Earth.  His false peace is broken by the rider on the Red Horse of verse 4.  The resulting war brings about the famine of the Black Horse in verse 6 and the disease of the Ashen Horse of verse 8:

7 When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, "Come."
8 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 ...
