Exodus 3:11-15

11And Moses said to 1God, Who am I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?

12And he said, For I will be with thee; and this shall be the sign to thee that I have sent thee: when thou hast brought forth the people out of Egypt, ye shall serve 2God upon this mountain.

13And Moses said to 3God, Behold, [when] I come unto the children of Israel, and shall say unto them, The 4God of your fathers hath sent me unto you; and they shall say, What is his name? what shall I say unto them?

14And 5God said to Moses, I AM THAT I AM. And he said, Thus shalt thou say unto the children of Israel: I AM hath sent me unto you.

15And 6God said moreover to Moses, Thus shalt thou say unto the children of Israel: Jehovah, the 7God of your fathers, the 8God of Abraham, the 9God of Isaac, and the 10God of Jacob, hath sent me unto you. This is my name for ever, and this is my memorial unto all generations.
