Exodus 3:12-15

3:12 He 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.”

3:13 Moses 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?”

3:14 God said to Moses, “I am that I am.” And he said, “You must say this to the Israelites, ‘I am has sent me to you.’” 3:15 God also said to Moses, “You must say this 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 my memorial from generation to generation.’
