'Astonishing' in the Bible

The man replied, “Well, this is astonishing! You do not know where He comes from, and yet He opened my eyes!

But a certain man, by name Simon, had been before in the city, using magic arts, and astonishing the nation of Samaria, saying that himself was some great one.

For you are bringing some astonishing things to our ears. Therefore we want to know what {these things mean}."
