Zechariah 6:5; Zechariah 6:7

5 And 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.
7 And 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.
