But so that you may see that on earth the Son of man has authority for the forgiveness of sins, then said he to the man who was ill, Get up, and take up your bed, and go to your house.
Matthew 9:6

1)Luk 5:21 And the scribes and Pharisees were having an argument, saying, Who is this, who has no respect for God? who is able to give forgiveness for sins, but God only?
