Revelation 6:5-6

And when he opened the third seal, I heard the third living creature saying, Come. And I saw, and behold, a black horse; and he that sat thereon had a balance in his hand.

And I heard as it were a voice in the midst of the four living creatures saying, A measure of wheat for a shilling, and three measures of barley for a shilling; and the oil and the wine hurt thou not.
