Exodus 3:13-15 Christian Standard Bible (CSB)
13 Then Moses asked God, “If 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 should I tell them?”
14 God replied to Moses, “I AM WHO I AM.[a] This is what you are to say to the Israelites: I AM has sent me to you.” 15 God also said to Moses, “Say this to the Israelites: The Lord, 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; this is how I am to be remembered in every generation.
