Exodus 3:11-13

11Moses said to God, “Who am I, that I should go to Pharaoh, or that I should bring the Israelites out of Egypt?”

12He replied, “Surely I will be with you, and this will be the sign to you that I have sent you: When you bring the people out of Egypt, you and they will serve God on this mountain.”

13Moses said to God, “If I go to the Israelites and tell them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ – what should I say to them?”
