Zechariah 6:3-6

3the third white horses, and the fourth dappled horses—all of them strong.

4So I inquired of the angel who was speaking with me, “What are these, my lord?”

5And the angel told me, “These are the four spirits1 of heaven, going forth from their station before the Lord of all the earth. 6The one with the black horses is going toward the land of the north, the one with the white horses toward the west,2 and the one with the dappled horses toward the south.”
