Zechariah 6:5-8

5And the angel answered and said unto me, These are the four spirits of the heavens, which go forth from standing before the Lord of all the earth.1

6The black horses which are therein go forth into the north country; and the white go forth after them; and the grisled go forth toward the south country.

7And the bay went forth, and sought to go that they might walk to and fro through the earth: and he said, Get you hence, walk to and fro through the earth. So they walked to and fro through the earth.

8Then cried he upon me, and spake unto me, saying, Behold, these that go toward the north country have quieted my spirit in the north country.
