WMF - Interesting synopsis, there has been a quite a bit of work looking at the roots of the of the God of Isreal. In fact the "El" in the name Isreal tells you a fair bit in itself.
Interesting to read what good old Wiki says about El and Yaweh
Another interesting read with a counter argument against the idea of Yaweh and El being the same god, still makes me think of Yaweh being a total jerk.
In my opinion worshipping Yaweh is like worshipping Hitler....
Except Hitler existed
