Zechariah 6:3 - And in the third chariot white horses; and in the fourth chariot grisled and bay H554 horses.
Zechariah 6:7 - And the bay H554 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.
