'Unrighteousness' in the Bible

{A Psalm of David.} Fret not thyself because of evil-doers, and be not envious of them that work unrighteousness;

To shew that Jehovah is upright: he is my rock, and there is no unrighteousness in him.

The upright shall see it, and rejoice; and all unrighteousness shall stop its mouth.

Who also do no unrighteousness: they walk in his ways.
