'Forgive' in the Bible

Why does this man thus speak? he blasphemes. Who is able to forgive sins except God alone?

But that ye may know that the Son of man has power on earth to forgive sins, he says to the paralytic,

And when ye stand praying, forgive if ye have anything against any one, that your Father also who is in the heavens may forgive you your offences.

But if ye do not forgive, neither will your Father who is in the heavens forgive your offences.
