the revelation 6:5-6

and when He has opened the third seal, have I heard the third living creature say: come! and have seen, and look a black horses; and the one, who is sat thereon, has had a scale in his hand. and I did hear as it were a voice midheaven of the four creatures say: a measure of wheat for a denarius, and three measures of barley for a denarius; and the oil and the wine shall you (SG) not damage.
