Revelation 6:5-8

5When the Lamb opened the third seal, I heard the third living creature say, “Come!” I looked, and there before me was a black horse! Its rider was holding a pair of scales in his hand.

6Then I heard what sounded like a voice among the four living creatures, saying, “Two pounds Or about 1 kilogram of wheat for a day’s wages, Greek a denarius and six pounds Or about 3 kilograms of barley for a day’s wages, Greek a denarius and do not damage the oil and the wine!” 7When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!”

8I looked, and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.
