Zechariah 6:4

And I turned, and lifted up mine eyes, and looked, and, behold, there came four chariots out from between two mountains; and the mountains were mountains of brass.

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

And in the third chariot white horses; and in the fourth chariot grisled and bay horses.

And 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.
