'Blaspheming' in the Bible

“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.
