'Iniquity' in the Bible

thou shalt not bow down thyself to them, nor serve them; for I, Jehovah thy God, am a jealous God, visiting the iniquity of the fathers upon the sons, and upon the third and upon the fourth generation of them that hate me,

One witness shall not rise up against a man for any iniquity, and for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall a matter be established.
