Tel Masos is believed to have played a big role in the mining and smelting activities associated with copper extraction in
Timna valley. It was a prosperous settlement at that time, being seen an important trading hub controlling copper production in the
Arabah. It also played a big role as a centre of incense trade at the northern extremity of the Arabian incense trading route. According to Na'aman, the Edomites constructed a centre at
Khirbet en-Nahas where the metallurgical production was concentrated, while Tel Masos coordinated the transportation and the territorial administration. == Egyptian influence ==
