'Iniquity' in the Bible

Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,

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

for the abomination of Jehovah thy God is any one doing these things, any one doing iniquity.

He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.
