Revelation 6:5-6

And when the Lamb opened the third seal, I heard the third living creature say, “Come!” Then I looked and saw a black horse, and its rider held in his hand a pair of scales.

And I heard what sounded like a voice from among the four living creatures, saying, “A quart of wheat for a denarius, and three quarts of barley for a denarius, and do not harm the oil and wine.”
