Exodus 3:12-15

12He answered, “I will certainly be with you, and this will be the sign to you that I am the one who sent you: when you bring the people out of Egypt, you will all worship God at this mountain.”

13Then Moses asked God, “If I go to the Israelites 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 replied to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: I AM has sent me to you.”

15God also said to Moses, “Say this to the Israelites: The Lord, 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 name forever; this is how I am to be remembered in every generation.
