'We Have Sinned' in the Bible

And they gathered together to Mizpeh, and drew water, and poured it out before the LORD, and fasted on that day, and said there, We have sinned against the LORD. And Samuel judged the children of Israel in Mizpeh.

And they cried unto the LORD, and said, We have sinned, because we have forsaken the LORD, and have served Baalim and Ashtaroth: but now deliver us out of the hand of our enemies, and we will serve thee.
