Very interesting,

It really makes you wonder when they had it right over 2000 years ago and we cant manage it today. I wonder if you can find anything in the bible about it, maybe I'll have a look. The Catholic/Orthodox bible has an extra five books in the Old Testament that the others dont use, maybe there is something in one of them, I doubt there would be anything in the New Testament. There are bound to be similarities between Judaism, Islam and Christianity, they are the three monotheistic religions (one God) and share the same History. They all follow the God of Abraham.
