Revelation 6:5-8

5Then when the Lamb opened the third seal I heard the third living creature saying, “Come!” So I looked, and here came a black horse! The one who rode it had a balance scale in his hand.

6Then I heard something like a voice from among the four living creatures saying, “A quart of wheat will cost a day’s pay and three quarts of barley will cost a day’s pay. But do not damage the olive oil and the wine!”

7Then when the Lamb opened the fourth seal I heard the voice of the fourth living creature saying, “Come!”

8So I looked and here came a pale green horse! The name of the one who rode it was Death, and Hades followed right behind. They were given authority over a fourth of the earth, to kill its population with the sword, famine, and disease, and by the wild animals of the earth.
