5 When he opened the third seal, I heard the third living creature say, "Come!" And I looked, and behold, a black horse! And its rider had a pair of scales in his hand. 6 And I heard what seemed to be a voice in the midst of 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!"
