Psalms 18:20-30

The LORD has dealt with me according to my righteousness; according to the cleanness of my hands he has rewarded me. For I have kept the ways of the LORD; I am not guilty of turning from my God. All his laws are before me; I have not turned away from his decrees. I have been blameless before him and have kept myself from sin. The LORD has rewarded me according to my righteousness, according to the cleanness of my hands in his sight. 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. As for God, his way is perfect: The LORD’s word is flawless; he shields all who take refuge in him.
