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.[b] This is what you are to say to the Israelites: “I am has sent me to you.”’
15 God also said to Moses, ‘Say to the Israelites, “The Lord,[c] the God of your fathers – the God of Abraham, the God of Isaac and the God of Jacob – has sent me to you.”
