Revelation 6:5-8

When He (the Lamb) broke open the third seal, I heard the third living creature call out, “Come.” I looked, and behold, a black horse [of famine]; and the rider had in his hand a pair of scales (a balance). [Zech 6:1-8] And I heard something like a voice in the midst of the four living creatures saying, “A quart of wheat for a denarius (a day’s wages), and three quarts of barley for a denarius; and do not damage the oil and the wine.” [2 Kin 6:25] When He (the Lamb) broke open the fourth seal, I heard the voice of the fourth living creature call out, “Come.” So I looked, and behold, an ashen (pale greenish gray) horse [like a corpse, representing death and pestilence]; and its rider’s name was Death; and Hades (the realm of the dead) was following with him. 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 by the wild beasts of the earth. [Ezek 14:21; Hos 13:14]
