Public buildings were found on the site, which were built at the beginning of the twelfth century BC and in which an Egyptian - Canaanite influence is evident.

Nadav Na’aman (2021) sees Tel Masos as playing a big role in Faynan copper economy, but he identifies this town with early Edom.

[3] 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.

[4] 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.

[5] The Pharaoh Shoshenq’s campaign to south Canaan may have played a big role in the history of this area, and it occasioned many academic debates.
