And when he had opened the third seal, I heard the third living creature saying: Come, and see. And behold a black horse, and he that sat on him had a pair of scales in his hand. And I heard as it were a voice in the midst of the four living creatures, saying: Two pounds of wheat for a penny, and thrice two pounds of barley for a penny, and see thou hurt not the wine and the oil.
