13 Moses 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?’ Then what shall I tell them?”
14 God said to Moses, “I am who I am.[C] This is what you are to say to the Israelites: ‘I am has sent me to you.’”
