Exodus 3:13-15

Moses said to God, “When I go to the Israelites, I will say to them, ‘The God of your ancestors sent me to you.’ What if the people say, ‘What is his name?’ What should I tell them?” Then God said to Moses, “I AM WHO I AM. When you go to the people of Israel, tell them, ‘I AM sent me to you.’ ” God also said to Moses, “This is what you should tell the people: ‘The LORD is the God of your ancestors—the God of Abraham, the God of Isaac, and the God of Jacob. He sent me to you.’ This will always be my name, by which people from now on will know me.
