'Confessed' in the Bible

After they had assembled at Mizpah, they drew water and poured it out before the Lord. They fasted on that day, and they confessed there, "We have sinned against the Lord." So Samuel led the people of Israel at Mizpah.

Then I confessed my sin; I no longer covered up my wrongdoing. I said, "I will confess my rebellious acts to the Lord." And then you forgave my sins. (Selah)

But have my words and statutes, which I commanded my servants the prophets, not outlived your fathers? Then they paid attention and confessed, 'The Lord who rules over all has indeed done what he said he would do to us, because of our sinful ways.'"
