'Blasphemeth' in the Bible

And, behold, certain of the scribes said within themselves, This man blasphemeth.

Why doth this man thus speak? he blasphemeth: who can forgive sins but one, even God?

And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.
