"When Moses asks his name and credentials, Yahweh replies with a pun which, as we shall see, would exercise monotheists for centuries. Instead of revealing his name directly, he answers: "I Am Who I Am (Ehyeh asher ehyeh)." ... When the Bible uses a phrase like: "they went where they went", it means: "I haven't the faintest idea where they went". So when Moses asks who he is, God replies in effect: "Never you mind who I am!" or "Mind your own business!""
