'Sinned' in the Bible

"I confess the sins that we Israelis have committed against you. Both I and my father's house have sinned. We have abandoned you by not keeping your commands, your ceremonies, and your judgments that you proscribed to your servant Moses.

You admonished them to return to your Law, but they acted arrogantly, and would not listen to your commands. They sinned against your regulations, which if anyone obeys, he will live by them. They turned away, being stubborn and stiff-necked, and they did not listen.
