It is silly to think that "nomadic shepherds" couldn't deal with counting flocks of hundreds of sheep.
Says who. Seems they did alright enough that every empire on earth around Israel wanted their possession. They also did alright enough that they gave rise to the richest and wisest man on the planet for a while - Solomon. Nothing more than a nomadic shepherd.. lol. For all you think you know, you guys are ignorant. Why is that.
