John 3:10 Art thou a master of Israel,

Greek : 

Literal Verse: 

You are a teacher of Israel and you have not learned to know these things?

KJV : 

Jhn 3:10 Art thou a master of Israel, and knowest not these things?

Interesting and Hidden Aspects: 

The KJV offers this as a question, but there is nothing in the Greek that prevents it from being a simple statement. A question would usually be introduced by an interrogative pronoun, which is missing here.

The word translated as "Master" primarily means "teacher." It was not the word that means "master" in the sense of a lord. It means master in the sense of a master of a subject.

The Greek word translated as "knowest" specifically means "learning to know" or "learning by contemplation." It also means to "perceive" or, as we might say, recognize. Christ seems to be saying that the teachers of Israel do not recognize the basic ontological concept of a spiritual birth that he is offering to him.
