Moshe said to God, "Behold, when I come to the children of Yisra'el, and tell them, 'The God of your fathers has sent me to you;' and they ask me, 'What is his name?' What should I tell them?"
God said to Moshe, "I AM WHO I AM," and he said, "You shall tell the children of Yisra'el this: "I AM has sent me to you."
God said moreover to Moshe, "You shall tell the children of Yisra'el this, 'The LORD, the God of your fathers, the God of Avraham, the God of Yitzchak, and the God of Ya`akov, has sent me to you.' This is my name forever, and this is my memorial to all generations.
