Psalms 101:4 - Coke's Commentary on the Holy Bible

A froward heart shall depart from me— Perverse hearts shall depart from me: I will not protect him who is evil. The word עקשׁ ikkesh, rendered perverse, signifies a man of a subtle disposition, who can twist and twine himself into all manner of shapes, and who has no truth or principle to be depended upon. "I will never regard, own, or treat such a one as my favourite and friend, says David, any more than if I had never known him."
