Exodus 3:12-15

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 1God upon this mountain.

13And Moses said to 2God, Behold, [when] I come unto the children of Israel, and shall say unto them, The 3God of your fathers hath sent me unto you; and they shall say, What is his name? what shall I say unto them?

14And 4God 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 5God said moreover to Moses, Thus shalt thou say unto the children of Israel: Jehovah, the 6God of your fathers, the 7God of Abraham, the 8God of Isaac, and the 9God of Jacob, hath sent me unto you. This is my name for ever, and this is my memorial unto all generations.
