Exodus 3:12-15

God answered, “I will be with you. And this is your sign that I am the one who has sent you: When you have brought the people out of Egypt, you will worship God at this very mountain.” But Moses protested, “If I go to the people of Israel and tell them, ‘The God of your ancestors has sent me to you,’ they will ask me, ‘What is his name?’ Then what should I tell them?” God replied to Moses, “I AM WHO I AM. Say this to the people of Israel: I AM has sent me to you.” God also said to Moses, “Say this to the people of Israel: Yahweh, the God of your ancestors—the God of Abraham, the God of Isaac, and the God of Jacob—has sent me to you.
