Duke Magdiel, Duke Iram,.... Magdiel also, Jerom says, was in the country of Gabalena, formerly possessed by the dukes of Edom; and the Targum of Jonathan says, this duke was called Magdiel from the name of his city, which was a strong "migdal" or tower: and Jarchi's note upon this word is, this is Rome; so the Jewish writers elsewhere say , that Esau had an hundred provinces from Seir to Magdiel; as it is said, "Duke Magdiel, Duke Iram", this is Rome:these [be] the dukes of Edom, according to their habitations, in the land of their possession; the former race of dukes, as has been observed, were dukes in the land of Edom, were sojourners in the land, at least had not sovereign dominion, or were not the only dukes in it; there were dukes of the race of Seir at the same time; but now these having driven out the Horites, were sole possessors and sovereign lords; and thus while Israel and his posterity were sojourners in a strange land, Esau and his family were possessors and lords of a country they could call their own:he [is] Esau the father of the Edomites; that is, Edom, the dukes of whose race are before reckoned up; the same is Esau, who had the name of Edom from selling his birthright for a mess of red pottage: and this is the man from whom the Edomites or Idumeans sprung, often hereafter spoken of in the Scripture, though no more in this history.
He is said to be killed by the tribes of Israel, at the funeral of Jacob, he coming forth with a great army to hinder his interment in the cave of Machpelah: it is a tradition of the Jews , he was slain by Judah.
