As the message was passed down through the generations, people would embellish the story, adding things here and there. When the Lord confused the languages at the tower of Babel, that is where His name branched into it's many forms. I believe the base form that most of the names of the Almighty stem from is YAH.
If you know the meaning of a good firm handshake and all that it implies, then you will understand YAH.
All Glory and Honor are yours Almighty YAH, forever and ever, Amen!
