Friday 13th phobia

I have been reading Esther and in the book is the account of the start of Purim which is celebrated on 13th & 14th days of the month of Adar (which is roughly in March in our calendar).
On the 13th day there was issued an edict to destroy all the jews, which the Persian King then turned around to declare that the day could be used so that the Jews could destroy all of their enemies and get away with it, without being prosecuted and brought to account before the King.
Checking out the origins of friday 13th phobia, there is a large degree of uncertainty as to how the phobia started, with many references being presented in greek literature and perhaps earlier than that, and the fact that many nations where Jews resided in history, i.e. germany, spain, etc have the same stories and phobia.
The jews celebrate Purim with noisebangers and 'graggers' which were used to scare of Haman and his sons; to rid themselves of the spirits of their enemies, who had plotted against them.
Therefore, it being on the 13th of the month, I think this has transferred itself into our culture, either as a way of being scared, or having a phobia of the Jews being able to attack and kill their enemies or by the Jews being afraid of their enemies about to attack them. I think the former is more likely.
So other cultures developed this fear that the 13th would bring them bad luck because the Jews were in control, could rout their enemies and save their land and their peoples and boy, the devil hates it, so he has turned it around to become associated with horror and occult and phobias, a fear where things can or may go wrong simply for getting out of bed on such a day.
The Jews celebrate freedom whilst the rest of the world trembles in fear and trepidation.
Well, the rest of the world ain't seen nothin' yet !!!
