Revelation 6:5-6

When he opened the third seal, I heard the third living creature say, “Come! ” And I looked, and there was a black horse.  Its rider held a set of scales in his hand.  Then I heard something like a voice among the four living creatures say, “A quart of wheat for a denarius,  and three quarts of barley for a denarius,  but do not harm the oil and the wine.”
