Exodus 3:14-15

And God answered unto Moses, I AM THAT I AM. And he said, Thus shalt thou say unto the sons of Israel: I AM (YHWH) has sent me unto you. And God said moreover unto Moses, Thus shalt thou say unto the sons of Israel: The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me unto you. This is my name for ever, and this is my memorial unto all ages.
