Psalm 18:25

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;

26With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself froward.

27For thou wilt save the afflicted people; but wilt bring down high looks.
