Zechariah 6:3-6

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

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

5The angel told me, “These are the four spirits of heaven going out after presenting themselves to the Lord of the whole earth.

6The one with the black horses is going to the land of the north, the white horses are going after them, but the dappled horses are going to the land of the south.”
