What is Blasphemy Against The Holy Ghost? - The Unforgivable Sin

Blasphemy (Greek blaptein, "to injure", and pheme, "reputation") signifies insulting or showing contempt or lack of reverence towards any person or thing worthy of exalted esteem.

The Bible speaks of blasphemy against the Holy Ghost as a sin which would not be forgiven in (Mat 12:31-32) saying:

(Mat 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.

(Mat 12:32) And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.

Blasphemy in the Old Testament against God as a whole could mean instantaneous death. Under the New Covenant, however, the bible speaks of blasphemy against the Holy Ghost only, as an unforgivable sin.
