13. suddenly--as if only waiting till their fellow had done.
      with the angel--who retires not, but is joined by others, come to seal and to celebrate the tidings he has brought.
      heavenly host--or "army," an army celebrating peace! [BENGEL] "transferring the occupation of their exalted station to this poor earth, which so seldom resounds with the pure praise of God" [OLSHAUSEN]; to let it be known how this event is regarded in heaven and should be regarded on earth.
