I looked up and saw a white horse. Its rider carried a bow, and a crown was placed on his head. He rode out to win many battles and gain the victory.

And another horse appeared, a red one. Its rider was given a mighty sword and the authority to remove peace from the earth. And there was war and slaughter everywhere.
When the Lamb broke the third seal, I heard the third living being say, "Come!" And I looked up and saw a black horse, and its rider was holding a pair of scales in his hand.
And a voice from among the four living beings said, "A loaf of wheat bread or three loaves of barley for a day's pay. And don't waste the olive oil and wine."
