Commentators highlight that Simeon uses the specific Greek word 'Despotes' for Lord, meaning 'Master,' while calling himself a 'slave.' His song is like that of a faithful watchman who, after a long and weary watch, is finally released from his post. His readiness to 'depart in peace' is a powerful image of a life of faithful service finding its joyful and complete fulfillment in God's perfect timing.
