13 And Moses said unto God, Behold, if I come unto the children of Israel, and say unto them, The God of your fathers hath sent me unto you; and they then say to me, What is his name? what shall I say unto them?

14 And God said unto Moses, I will be that I will be: and he said, Thus shalt thou say unto the children of Israel, I will be hath sent me unto you.
