"He Will Be the Mouthpiece"--is a direct quote from Exodus 4:16, The New English Bible (Oxford, 1970).
Moses is almost but not quite dumbstruck, because, get this, he starts to argue with the Creator! And this is where it gets good, Moses tells God, hey, I'm not very good with words! So this is where Yahweh says, Moses, you got a brother Aaron, right? You two are going to be partners and I'm going to tell you what I want done, then in turn, you're going to tell Aaron what I want done, capeesh? "He will be the mouthpiece!"
Thus, the Creator of the Universe formed a partnership, Moses and Aaron, LLC and the rest so to speak is history. Now, hear me--this is very important, all my words, all of your words, all of our insights are meaningless unless we open our hearts and minds to the 99% of reality that we do not see with our eyes. Anything is possible!
