'We Have Sinned' in the Bible

We lie down in our shame, and our confusion covereth us: for we have sinned against the LORD our God, we and our fathers, from our youth even unto this day, and have not obeyed the voice of the LORD our God.

Why do we sit still? assemble yourselves, and let us enter into the defenced cities, and let us be silent there: for the LORD our God hath put us to silence, and given us water of gall to drink, because we have sinned against the LORD.

O LORD, though our iniquities testify against us, do thou it for thy name's sake: for our backslidings are many; we have sinned against thee.

We acknowledge, O LORD, our wickedness, and the iniquity of our fathers: for we have sinned against thee.
