Exodus 3:13 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?
In Egyptian mysteries religion the name of a god denoted that god’s characteristics, and that characteristic was directly associated to some specific part of the natural or spiritual world that he, or she, had control or influence over.
So, if one was to match up the particular matter of concern to you with the right god, and then knew that god’s name, you could call out and that god had no choice but to do your bidding. If the land was dry you prayed to the god or goddess of rain, or water, or the river.
3:14 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.
God obliged and gave Moses a name: a name that denoted God’s characteristics, and that name was “ehyeh asher ehyeh.” In Hebrew this means ‘to bring into existence all that exists’ God gave us that “name” for just this reason, His name is not to be compared with anything, or anyone, else. He has power over ALL that exists.
