I am overawed by the predictive power of Leviticus, if I’m right in thinking that that’s the book that set the rules for orthodox jews.

As far as I can make out, from this BBC story, (Light sensors cause religious row) orthodox jews aren’t allowed to see by electric light on holy days.

A couple have taken legal action after claiming motion sensors installed at their holiday flat in Dorset breached their rights as Orthodox Jews.
Gordon and Dena Coleman said they cannot leave or enter their Bournemouth flat on the Sabbath because the hallway sensors automatically switch on lights.
The couple’s religious code bans lights and other electrical equipment being switched on during Jewish holidays.

I can’t understand the problem, here. If the hallway sensors detect that it’s dark – the outside world will have street lighting, surely.

So the litigious couple can’t go in the street anyway, as far as I can see. Because then they would be in non-kosher electric light anyway….

Unless street-lighting doesn’t count because those lights are already on when the couple leave their home. In which case, I suggest that they trick the sensors and just switch the lights on permanently in advance of any jewish holiday… Lateral thinking, hey?.

Did Leviticus ban all electric light? Or just proscribe electric light switches and motion sensors but say some lights were acceptably kosher?

As I said at the beginning – this rulebook seems so amazingly farsighted. There must have been real prophets at work, if they foresaw electric lighting a few thousand years ago. Is there anything in there about when we get the jetpacks?
