Matthew 12:31

διὰ τοῦτο connects not merely with preceding verse, but with the whole foregoing argument. Mark more impressively introduces the blasphemy logion with a solemn ἀμὴν λέγω ὑμῖν. πᾶσα ἁμαρτία, etc. A broad preliminary declaration of the pardonableness of human sin of all sorts, and especially of sins of the tongue, worthy and characteristic of Jesus, and making what follows more impressive. ἡ δὲ τ. Π. βλας. οὐκ ἀφεθήσεται : pointed, emphatic exception. Evidently the Spirit here is taken ethically. He represents the moral ideal, the absolutely good and holy. Blasphemy against the Spirit so conceived, unpardonable that is our Lord's deliberate judgment. βλασφημία, injurious speech (from βλάπτω and φήμη), in such a case will mean speaking of the holy One as if He were unholy, or, in the abstract, calling good evil, not by misunderstanding but through antipathy to the good.
