'Sins' in the Bible

For the transgression of Jacob is all this, and for the sins of the house of Israel. What is the transgression of Jacob? is it not Samaria? and what are the high places of Judah? are they not Jerusalem?

Therefore also will I make thee sick in smiting thee, in making thee desolate because of thy sins.

He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea.
