'Transgressions' in the Bible

Then I acknowledged my sin to Youand did not conceal my iniquity.I said,“I will confess my transgressions to the Lord,”and You took away the guilt of my sin.Selah

Deliver me from all my transgressions;do not make me the taunt of fools.

As far as the east is from the west,so far has He removedour transgressions from us.
