'Blaspheming' in the Bible

Now I have told him that I am about to judge his house forever for the sinful behavior which he knew [was happening], because his sons were bringing a curse on themselves [dishonoring and blaspheming God] and he did not rebuke them.

“Why does this man talk that way? He is blaspheming; who can forgive sins [remove guilt, nullify sin’s penalty, and assign righteousness] except God alone?”

[if that is true] then do you say of Him whom the Father sanctified and set apart for Himself and sent into the world, ‘You are blaspheming,’ because I said, ‘I am the Son of God’?

And he opened his mouth to speak blasphemies (abusive speech, slander) against God, to blaspheme His name and His tabernacle, and those who live in heaven.
