Revelation 6:5-8

5When he opened the third seal, I heard the third living creature say, “Come!” And I looked, and there was a black horse. Its rider held a set of scales in his hand.

6Then I heard something like a voice among the four living creatures say, “A quart of wheat for a denarius, and three quarts of barley for a denarius, but do not harm the oil and the wine.”

7When he opened the fourth seal, I heard the voice of the fourth living creature say, “Come!”

8And I looked, and there was a pale green horse. Its rider was named Death, and Hades was following after him. They were given authority over a fourth of the earth, to kill by the sword, by famine, by plague, and by the wild animals of the earth.
