Revelation 6:5-6

5Then when the Lamb opened the third seal I heard the third living creature saying, “Come!” So I looked, and here came a black horse! The one who rode it had a balance scale in his hand.

6Then I heard something like a voice from among the four living creatures saying, “A quart of wheat will cost a day’s pay and three quarts of barley will cost a day’s pay. But do not damage the olive oil and the wine!”
