Blasphemy against the Holy Spirit

The Bible says that blasphemy against the Holy Spirit will not be forgiven Matthew 12:31. In Matthew, this statement follows the broader declaration that every sin and blasphemy will be forgiven people, except blasphemy against the Spirit Matthew 12:31. The next verse distinguishes speaking against the Son of Man, described as forgivable, from speaking against the Holy Spirit, described as unforgivable “in this age or in the age to come” Matthew 12:32. Luke records the same contrast Luke 12:10. The word or idea recurs in at least 3 verses across 2 books and 2 episodes.
