The Third Seal. . . A Black Horse
Revelation 6:5-6
"And when He opened the Third Seal, I heard the Third Beast say, Come. And I beheld, and lo a Black Horse: and he that sat on him had a pair of balances in his hand.
And I heard a voice in the midst of the Four Beasts say, a measure of wheat for a penny, and three measures of barley for a penny: and see thou hurt not the oil and the wine."
When the Third Seal was broken John heard the third Man-like Living Creature say Come, and a Black Horse appeared and went forth, whose Rider held in his hand a pair of balances and John heard the voice of an invisible person in the middle of the Four Living Creature speak.
The Black Horse represents famine and the Rider keeper of food.
