Exodus Chapter 3, Verse 14
From BibleWiki
14: 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.
14: And God spoke to Moses, saying, I am THE BEING; and he said, Thus shall ye say to the children of Israel, THE BEING has sent me to you.
God therefore told him His name, or, to speak more correctly, He explained the name יהוה, by which He had made Himself known to Abraham at the making of the covenant (Gen 15:7), in this way, אהיה אשׁר אהיה, "I am that I am," and designated Himself by this name as the absolute God of the fathers, acting with unfettered liberty and self-dependence. This name precluded any comparison between the God of the Israelites and the deities of the Egyptians and other nations, and furnished Moses and his people with strong consolation in their affliction, and a powerful support to their confidence in the realization of His purposes of salvation as made known to the fathers.
