Peer Pressure

[Torchwatch]

The Covenant of Abraham in which God gave the Land of Canaan to Abraham and his followers in return for circumcision and worship took place in the Bronze Age. What they could have done with would have been a weapon against which no equally sized army or city could stand up against. That weapon would have been iron which humanity would discover some 600 years later anyway.
At the time of King Saul the Israelites still didn't have a blacksmith although the Iron Age had begun. So what is it with God that while handing out divine inspiration he doesn't hand out technological advances that would allow his chosen people to survive and prosper?

It would be very difficult to weave, cut and sew swim briefs without iron and steel tools.
