View [Shmot 3:13-15](http://www.mechon-mamre.org/p/pt/pt0203.htm).

In verse 13, Moshe asks G-d what name of G-d should he tell B'nai Yisra'el.

In verse 14, G-d first answers I AM THAT I AM, and then says just I AM.

Fine, I am aware of Rashi's explanation of the conversation Moshe had with G-d regarding omitting "that I AM".

But, in verse 15, G-d says, "G-d, G-d of your fathers, Avraham, Yitzhak and Ya'akov..." and finally the verse ends, "THIS is my name..."

What is the meaning of G-d apparently giving Moshe different answers to what seems like a simple question? Is Moshe supposed to relay **all** these names? If it's just one, which one is it?
