Blasphemy against the Holy Spirit

““Therefore I say to you, every sin and blasphemy shall be forgiven people, but blasphemy against the Spirit shall not be forgiven. And whoever speaks a word against the Son of Man, it shall be forgiven him; but whoever speaks against the Holy Spirit, it shall not be forgiven him, either in this age or in the age to come.” ‭‭Matthew‬ ‭12‬:‭31‬-‭32‬ ‭NASB2020‬‬

I’ve seen too many people confused on this.
