Zechariah 6:3-6

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

4Then I answered and said to the angel who talked with me, "What are these, my lord?"

5And the angel answered and said to me, "These are going out to the four winds of heaven, after presenting themselves before the Lord of all the earth.

6The chariot with the black horses goes toward the north country, the white ones go after them, and the dappled ones go toward the south country."
