You, LORD, keep my lamp burning — photo by David Kitz

To the faithful you show yourself faithful,
    to the blameless you show yourself blameless,
to the pure you show yourself pure,
    but to the devious you show yourself shrewd.
You save the humble
    but bring low those whose eyes are haughty.
You, LORD, keep my lamp burning;
    my God turns my darkness into light.
With your help I can advance against a troop;
    with my God I can scale a wall.
