Psalms 18:20-26

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.
