'Iniquity' in the Bible

you shall not bow down yourself to them, nor serve them; for I, Yahweh, your God, am a jealous God, visiting the iniquity of the fathers on the children, and on the third and on the fourth generation of those who hate me;

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

The Rock, his work is perfect, for all his ways are justice: a God of faithfulness and without iniquity, just and right is he.
