'Iniquity' in the Bible

Therefore, O king, let my advice be acceptable [to you] and your sin remove with righteousness and your iniquity with having mercy on [the] oppressed, {in case there might be a prolongation of your prosperity}.'"

We have sinned, and have committed iniquity, and have done wickedly, and have rebelled, even by departing from thy precepts and from thy judgments:

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 are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
