2 Samuel 22:22-27

For I have kept the ways of the LORD; I have not turned from my God to follow evil. I have followed all his regulations; I have never abandoned his decrees. I am blameless before God; I have kept myself from sin. The LORD rewarded me for doing right. He has seen my innocence. “To the faithful you show yourself faithful; to those with integrity you show integrity. To the pure you show yourself pure, but to the crooked you show yourself shrewd.
