'Sinned' in the Bible

Let thine ear now be attentive, and thine eyes open, that thou mayest hear the prayer of thy servant, which I pray before thee now, day and night, for the children of Israel thy servants, and confess the sins of the children of Israel, which we have sinned against thee: both I and my father's house have sinned.

And testifiedst against them, that thou mightest bring them again unto thy law: yet they dealt proudly, and hearkened not unto thy commandments, but sinned against thy judgments, (which if a man do, he shall live in them;) and withdrew the shoulder, and hardened their neck, and would not hear.
