'Wrong doing' in the Bible

How blessed is the one whose wrongdoing the Lord does not punish, in whose spirit there is no deceit.

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)

Yes, I confess my wrongdoing, and I am concerned about my sins.

Wash away my wrongdoing! Cleanse me of my sin!

You pardoned the wrongdoing of your people; you forgave all their sin. (Selah)
