Some years I read a book about a man who travelled around the lands featured in biblical texts. He was looking at the bible from an historical point of view. He was visiting various sites mentioned in the texts. Even then he had to negeotiate military check points. One of the places he visited was Saint Catherine's monastery in the Sinal desert.
The big claim to fame of Saint Catherine's monastery is that the monks who reside there claim that they have THE original burning bush, the one through which the Almighty caused to burst into flame and not burn while the Almighty conversed with Moses.
Anyway, there is our hero, looking at the bush in the calm of a Sinal evening in the little yard in the monastery when something catches his eye...a fire extinguisher!
I often wondered what would have happened if the bush had flared up into flame and a voice claiming to be the Almighty started pontificating from within it and the monks had cut lose with the fire extinguisher......
It's a good travel book to read. It is Walking the Bible by Bruce Feiler
