Exodus 3:12-15

12“I will surely be with you,” God said, “and this will be the sign to you that I have sent you: When you have brought the people out of Egypt, all of you will worship God on this mountain.”1

13Then Moses asked God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is His name?’ What should I tell them?”

14God said to Moses, “I AM WHO I AM.2 This is what you are to say to the Israelites: ‘I AM has sent me to you.’”

15God also told Moses, “Say to the Israelites, ‘The LORD, the God of your fathers—the God of Abraham, the God of Isaac, and the God of Jacob—has sent me to you.’ This is My name forever, and this is how I am to be remembered in every generation.
