Exodus 3:13-15

13But 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?”

14God replied to Moses, “I Am Who I Am. Say this to the people of Israel: I Am has sent me to you.”

15God 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. This is my eternal name, my name to remember for all generations.
