Zechariah 6:3-6

3and in the third chariot white horses; and in the fourth chariot grizzled strong horses.

4Then I answered and said unto the angel that talked with me, What are these, my lord?

5And the angel answered and said unto me, These are the four winds of heaven, which go forth from standing before the Lord of all the earth.

6The chariot wherein are the black horses goeth forth toward the north country; and the white went forth after them; and the grizzled went forth toward the south country.
