'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 I also have smitten thee with a grievous wound; I have made thee desolate because of thy sins.

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