¹³ And Moses saith unto God, `Lo, I am coming unto the sons of Israel, and have said to them, The God of your fathers hath sent me unto you, and they have said to me, What [is] His name? what do I say unto them?'

¹⁴ And God saith unto Moses, `I Am That Which I Am;' He saith also, `Thus dost thou say to the sons of Israel, I Am hath sent me unto you.'

¹⁵ And God saith again unto Moses, `Thus dost thou say unto the sons of Israel, Jehovah, God of your fathers, God of Abraham, God of Isaac, and God of Jacob, hath sent me unto you; this [is] My name -- to the age, and this My memorial, to generation -- generation.
