Exodus 3:11-14 Darby Translation 1890 (DARBY)

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

12. And 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 God upon this mountain.

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

14. And God 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.
