Exodus 3:14-15

And God said to Moses, I AM WHO I AM and WHAT I AM, and I WILL BE WHAT I WILL BE; and He said, You shall say this to the Israelites: I AM has sent me to you! God said also to Moses, This shall you say to the Israelites: The Lord, the God of your fathers, of Abraham, of Isaac, and of Jacob, has sent me to you! This is My name forever, and by this name I am to be remembered to all generations.
