Exodus 3:13-15

13Then Moses replied to God, “Suppose I go to the people of Israel and say to them, ‘The God of your ancestors has sent me to you,’ and they ask me, ‘What is his name?’ What should I tell them?”

14God answered Moses, “I Am Who I Am. This is what you must say to the people of Israel: ‘I Am has sent me to you.’ ”

15Again God said to Moses, “This is what you must say to the people of Israel: The Lord God of your ancestors, the God of Abraham, Isaac, and Jacob, has sent me to you. This is my name forever. This is my title throughout every generation.
