'Sinned' in the Bible

Then the {Israelites} cried out to Yahweh, saying, "We have sinned against you; we have abandoned our God and served the Baals."

And the {Israelites} said to Yahweh, "We have sinned; {do to us accordingly as you see fit}; only please deliver us this day."

I have not sinned against you; but you [are] the one who is doing wrong by making war against me. {Let Yahweh judge} today between the {Israelites} and the {Ammonites}."
