Psalm 18:21-26

21For I have kept the ways of the LORD ; I am not guilty of turning from my God.

22All his laws are before me; I have not turned away from his decrees.

23I have been blameless before him and have kept myself from sin.

24The LORD has rewarded me according to my righteousness, according to the cleanness of my hands in his sight.

25To the faithful you show yourself faithful, to the blameless you show yourself blameless,

26to the pure you show yourself pure, but to the devious you show yourself shrewd.
