'Iniquity' in the Bible

we have sinned, committed iniquity, acted wickedly and rebelled, even turning aside from Your commandments and ordinances.

As it is written in the law of Moses, all this calamity has come on us; yet we have not sought the favor of the Lord our God by turning from our iniquity and giving attention to Your truth.

“Seventy weeks have been decreed for your people and your holy city, to finish the transgression, to make an end of sin, to make atonement for iniquity, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the most holy place.
