Psalm 18:24-26

American Standard Version

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;
²⁶ With the pure thou wilt show thyself pure;
And with the perverse thou wilt show thyself froward.
