'Pardon' in the Bible

Be on your guard before Him, listen to and obey His voice; do not be rebellious toward Him or provoke Him, for He will not pardon your transgression, since My Name (authority) is in Him.

And he said, “If now I have found favor and lovingkindness in Your sight, O Lord, let the Lord, please, go in our midst, though it is a stiff-necked (stubborn, rebellious) people, and pardon our iniquity and our sin, and take us as Your possession.”
