In the reply of the guards this man seems to be emphatic.

Their response must be understood as a reference to the content of what Jesus had said. It would be wrong to suggest that there was something unusual about Jesus’ manner of speech or his accent or pronunciation. One may say in some languages “No one has ever said the things this man has said” or “What this man has said is different from what all other men have said.”
