Revelation 6:5-6

5When He (the Lamb) broke open the third seal, I heard the third living creature call out, “Come.” I looked, and behold, a black horse [of famine]; and the rider had in his hand a pair of scales (a balance).

6And I heard something like a voice in the midst of the four living creatures saying, “A quart of wheat for a denarius (a day’s wages), and three quarts of barley for a denarius; and do not damage the oil and the wine.”
