Exodus 3:13-15 Common English Bible (CEB)
God’s special name
13 But Moses said to God, “If I now come to the Israelites and say to them, ‘The God of your ancestors has sent me to you,’ they are going to ask me, ‘What’s this God’s name?’ What am I supposed to say to them?”
14 God said to Moses, “I Am Who I Am.[a] So say to the Israelites, ‘I Am has sent me to you.’” 15 God continued, “Say to the Israelites, ‘The Lord, the God of your ancestors, Abraham’s God, Isaac’s God, and Jacob’s God, has sent me to you.’ This is my name forever; this is how all generations will remember me.
