'Sinned' in the Bible

And the people of Israel cried to the LORD, saying, "We have sinned against thee, because we have forsaken our God and have served the Ba'als."

And the people of Israel said to the LORD, "We have sinned; do to us whatever seems good to thee; only deliver us, we pray thee, this day."

I therefore have not sinned against you, and you do me wrong by making war on me; the LORD, the Judge, decide this day between the people of Israel and the people of Ammon."
