Zechariah 6:4

2In the first chariot were red horses; and in the second chariot black horses;

3And in the third chariot white horses; and in the fourth chariot grisled and bay 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 spirits of the heavens, which go forth from standing before the LORD of all the earth.

6The black horses which are therein go forth into the north country; and the white go forth after them; and the grisled go forth toward the south country.
