'Pardon' in the Bible

Take ye heed before him, and hearken unto his voice; provoke him not; for he will not pardon your transgression: for my name is in him.

And he said, If now I have found favor in thy sight, O Lord, let the Lord, I pray thee, go in the midst of us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.
