'Educated' in the Bible

All vision has become to you like the words of a book that is sealed, which men deliver to one who is educated, saying, "Read this, please;" and he says, "I can't, for it is sealed:"

and the book is delivered to one who is not educated, saying, "Read this, please;" and he says, "I can't read."

The Jews therefore marveled, saying, "How does this man know letters, having never been educated?"
