'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 the high places of Judah? Is it not Jerusalem?

And I also, I have begun to smite thee, To make desolate, because of thy sins.

He doth turn back, He pitieth us, He doth subdue our iniquities, And Thou castest into the depths of the sea all their sins.
