Exodus 3:10-14

10Now go, for I am sending you to Pharaoh. You must lead my people Israel out of Egypt.”

11But Moses protested to God, “Who am I to appear before Pharaoh? Who am I to lead the people of Israel out of Egypt?”

12God 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.”

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.”
