Isa 43:25  I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins

Mk 2:7  Why doth this man thus speak blasphemies? who can forgive sins but God only? 

Lk 5:21  And the scribes and the Pharisees began to reason, saying, Who is this which speaketh blasphemies? Who can forgive sins, but God alone?
