Zechariah 6:3-8
6:3 to the third white horses, and to the fourth spotted horses, all of them strong.
6:4 Then I asked the angelic messenger who was speaking with me, “What are these, sir?”
6:5 The messenger replied, “These are the four spirits of heaven that have been presenting themselves before the Lord of all the earth.
6:6 The chariot with the black horses is going to the north country and the white ones are going after them, but the spotted ones are going to the south country.
6:7 All these strong ones are scattering; they have sought permission to go and walk about over the earth.” The Lord had said, “Go! Walk about over the earth!” So they are doing so.
6:8 Then he cried out to me, “Look! The ones going to the northland have brought me peace about the northland.”
