Exodus 3:11-13 Darby Translation (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?
