'Sins' in the Bible

"All this is for the disobedience of Jacob, and for the sins of the house of Israel. What is the disobedience of Jacob? Isn't it Samaria? And what are the high places of Judah? Aren't they Jerusalem?

Therefore I also have struck you with a grievous wound. I have made you desolate because of your sins.

He will again have compassion on us. He will tread our iniquities under foot; and you will cast all their sins into the depths of the sea.
