'We Have Sinned' in the Bible

Who gave Jacob for a spoil, and Israel to the robbers? did not the LORD, he against whom we have sinned? for they would not walk in his ways, neither were they obedient unto his law.

Thou meetest him that rejoiceth and worketh righteousness, those that remember thee in thy ways: behold, thou art wroth; for we have sinned: in those is continuance, and we shall be saved.
