Revelation 6:5-6

When He broke open the third seal, I heard the third living creature call out, Come and look ! And I saw, and behold, a black horse, and in his hand the rider had a pair of scales (a balance). And I heard what seemed to be a voice from the midst of the four living creatures, saying, A quart of wheat for a denarius [a whole day's wages], and three quarts of barley for a denarius; but do not harm the oil and the wine! [II Kings 6:25.]
