It had happened that when David was at Edom, Joab the commander of the army went up to bury the slain, and he killed every male in Edom.

There was not a king in Edom; a governor [served] as king.

King Solomon also built a fleet of ships at Ezion-Geber which [is] near Elath on the shore of the {Red Sea} in the land of Edom.

Then Yahweh raised an adversary against Solomon, Hadad the Edomite, from the descendants of that king in Edom.

For Joab and all Israel had stayed there six months until he exterminated every male in Edom.
