Zechariah 6:5-8

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.”

7As the strong horses went out, they were eager to go and patrol the earth; and the LORD said, “Go and patrol the earth.” So they patrolled the earth.

8Then the LORD summoned me and said, “Behold, those going to the land of the north have given rest to My Spirit in the land of the north.”
