In Numbers 14 we read about the 12 spies of Israel sent into the Promised Land to scope out Israel’s eventual homeland. No mention is made if they hired Realtors or not, although they drafted two reports as a result of the trip. One report by Joshua and Caleb and one report by the other ten.
One can infer from the text that each man sent was one of his tribes best. However, no mention is made of the requirements, qualifications, or skills needed to be the best. Were they the smartest (IQ), most charismatic, strongest, loudest, most pious, richest, or was it based on nepotism, they were the oldest of the tribes literal lineage to whichever son of Israel bore the name of the tribe?
