Revelation 6:5-8

5When the Lamb opened the third seal, I heard the third living creature saying, “Come!” And behold, I saw a black horse. The one riding on it held a balance scale in his hand.

6Then I heard something like a voice in the midst of the four living creatures saying, “A quart of wheat for a denarius, and three quarts of barley for a denarius—but do no harm to the oil and wine!”

7When the Lamb opened the fourth seal, I heard the fourth living creature saying, “Come!”

8Behold, I saw a horse, pale greenish gray. The name of the one riding on it was Death, and Sheol was following with him. Authority was given to them over a fourth of the earth, to kill by sword and by famine and by plague and by the wild beasts of the earth.
