What it means

A plain-English reading of the word, with the lexicons it draws on — Abbott-Smith, Strong's, and Liddell-Scott-Jones — right below it, in full.

AI Summary

βλασφημέω means to speak impiously or irreverently about God or sacred things, that is, to blaspheme 1234. This includes speaking against God himself, against his name, against glorious beings, and specifically against the Holy Spirit 1.

It also carries a distinct, more general sense: to speak evil of a person, to revile, slander, or defame them 123. In the passive it describes someone being spoken evil of or having their name maligned 13.
