Exodus 3:13-14

13Then Moses said to God, “If I come to the people of Israel 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 say to them?” 14God said to Moses, “I am who I am.”
Or  I am what I am, or  I will be what I will be
And he said, “Say this to the people of Israel: bI am has sent me to you.’”
