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?

3:13 As recorded in 3:14-15 God responds: I AM THAT I AM (אהיה אשר אהיה Ehyeh asher ehyeh) / Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. / Thus shalt thou say unto the children of Israel, the LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations.
