Revelation 6:5-6

5 When he opened the third seal, I heard the third living creature saying, "Come and see!" And behold, a black horse, and he who sat on it had a balance in his hand.  6 I heard a voice in the midst of the four living creatures saying, "A choenix of wheat for a denarius, and three choenix of barley for a denarius! Don't damage the oil and the wine!"
