The LORD rewarded me according to my righteousness; according to the cleanness of my hands he recompensed me. For I have kept the ways of the LORD, and have not wickedly departed from my God. For all his ordinances were before me, and from his statutes I did not turn aside. I was blameless before him, and I kept myself from guilt. Therefore the LORD has recompensed me according to my righteousness, according to my cleanness in his sight.
