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.’”
