I think there is enough historical evidence to rely on rather then the bible that is - no offence - probably not that accurate...
@heisme
I think the period you are going for is really really interessting, if it does work out I am your number one fan.
Yet I would try and define what exact time you are trying to focus on... a lot of different empires and states appeared...
@all
Any Mod on anything between 1500 - 700 would have my fullest support - would be very glad to provide infos as the military historian... P2P me..
