Psalms 18:26

With the pure -Those who are pure in their thoughts, their motives, their conduct. Thou wilt show thyself pure -They will find that they have to deal with a God who is himself pure; who loves purity, and who will accompany it with appropriate rewards wherever it is found. And with the froward -The word used here -עקשׁ‛iqqêsh- means properly perverse; a man of a perverse and wicked mind. It is derived from a verb -עקשׁ‛âqash- which means, to turn the wrong way, to wrest, to pervert.
