'Blaspheming' in the Bible

Then some of the experts in the law said to themselves, "This man is blaspheming!"

"Why does this man speak this way? He is blaspheming! Who can forgive sins but God alone?"

do you say about the one whom the Father set apart and sent into the world, 'You are blaspheming,' because I said, 'I am the Son of God'?
