In context
11But Moses said to God, “Who am I, that I should go to Pharaoh and bring the Israelites out of Egypt?” 12He answered, “I will be with you. And this will be the sign to you that I have sent you: when you have brought the people out of Egypt, you will worship God on this mountain.” 13Moses said to 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 shall I tell them?” 14God said to Moses, “I Am Who I Am.” And he said, “Tell the Israelites this: ‘I Am has sent me to you.’” 15God said further to Moses, “Tell the Israelites this: ‘Yahweh, 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 title for every generation.
