'Unrighteousness' in the Bible

If iniquity be in thy hand, put it far away, And let not unrighteousness dwell in thy tents.

If thou return to the Almighty, thou shalt be built up, If thou put away unrighteousness far from thy tents.

The womb shall forget him; The worm shall feed sweetly on him; He shall be no more remembered; And unrighteousness shall be broken as a tree.

Surely my lips shall not speak unrighteousness, Neither shall my tongue utter deceit.

Who hath enjoined him his way? Or who can say, Thou hast wrought unrighteousness?
