Zechariah 6:5; Zechariah 6:7

5 And the angel answered and said to 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, Go hence, walk to and fro through the earth. So they walked to and fro through the earth.
