Psalm 18:23-25

American Standard Version

²³ I was also perfect with him,
And I kept myself from mine iniquity.
²⁴ Therefore hath Jehovah recompensed me according to my righteousness,
According to the cleanness of my hands in his eyesight.
²⁵ With the merciful thou wilt show thyself merciful;
With the perfect man thou wilt show thyself perfect;
