When 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. Then I heard what sounded like a voice among the four living creatures, saying, "A quart of wheat for a day's wages, and three quarts of barley for a day's wages, and do not damage the oil and the wine!"
— revelation 6:5-6
The third horseman rides a black horse and is generally understood as Famine.The horseman carries a pair of balances or weighing scales, indicating the way that bread would have been weighed during a famine.
Of the four horsemen, the black horse and its rider are the only ones whose appearance is accompanied by a vocal pronunciation.
