Psalm 18:23

21For I have kept the ways of the LORD, and have not wickedly departed from my God.

22For all his judgments were before me, and I did not put away his statutes from me.

23I was also upright before him, and I kept myself from mine iniquity.

24Therefore hath the LORD recompensed me according to my righteousness, according to the cleanness of my hands in his eyesight.

25With the merciful thou wilt shew thyself merciful; with an upright man thou wilt shew thyself upright;
