And [God] said, "I will be with you; that shall be your sign that it was I who sent you. And when you have freed the people from Egypt, you shall worship God at this mountain." Moses said to God, "When I come to the Israelites and say to them, 'The God of your fathers' [house] has sent me to you,' and they ask me, 'What is [God's] name?' what shall I say to them?" And God said to Moses, "Ehyeh-Asher-Ehyeh," continuing, "Thus shall you say to the Israelites, 'Ehyeh sent me to you.'"
And he said, Certainly I will be with thee; and this shall be a token unto thee, that I have sent thee: When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain. And Moses said unto 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 to me, What is his name? what shall I say unto them? And God said unto 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.
