'Iniquity' in the Bible

Why dost thou shew me iniquity, and cause me to behold grievance? for spoiling and violence are before me: and there are that raise up strife and contention.

Thou art of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, and holdest thy tongue when the wicked devoureth the man that is more righteous than he?

Woe to him that buildeth a town with blood, and stablisheth a city by iniquity!
