'Sinned' in the Bible

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

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