'Iniquity' in the Bible

I will make him know that I am about to judge his household forever because of the iniquity that he knew, for his sons [were] bringing curses on themselves, but he did not rebuke them.

Therefore I swore to the house of Eli [that] the iniquity of the house of Eli would not be atoned for by sacrifice or by offering forever."

For rebellion [is like] the sin of divination; arrogance [is like] iniquity and idolatry. Because you have rejected the word of Yahweh, he has rejected you from [being] king!"
