Psalm 18:25-29

With the merciful you show yourself merciful; with the blameless man you show yourself blameless; with the purified you show yourself pure; and with the crooked you make yourself seem tortuous. For you save a humble people, but the haughty eyes you bring down. For it is you who light my lamp; the LORD my God lightens my darkness. For by you I can run against a troop, and by my God I can leap over a wall.
