Matthew Poole and continuators on Obadiah 1:19

19 And they of the south shall possess the mount of Esau, and they of the plain , the Philistines ; and they shall possess the fields of Ephraim , and the fields of Samaria , and Benjamin shall possess Gilead .

The Iewes who lived in the South parts of Canaan, which was next to Idumea, shall after their return and victories over Edom possess his Country, called here the Mount of Esau.

The Iewes who dwelt in the plain Country, which was next to Palestina, Iosh. 15.33.

Shall enlarge their borders, and possess the Philistines Country, together with their antient inheritance, now of the possession of Mount Esau by the Iewes, saith Grotius, it was most fully accomplisht by Hircanus. Iosesephus Lib. 13. chap. 17. reports the matter thus, that the Idumeans were commanded either to depart their Country, or be Circumcised. If this were the time of fulfilling the one, 'twas also the time of fulfilling the other also.

And all the land which the ten Tribes once did possess, shall again be possessed by the Jewes.

The fields also about Samaria, how greatly soever wasted, shall be replanted, and that by the Jewes too.

Either apart, or jointly with Judah.

A Country beyond Jordan, assigned to the Tribes of Reuben, Gad, and half Manasseh, wasted by Hazael and Tiglath Pileser, some time before Samaria was taken, but should be inhabited by the Benjamites; And probably Gad, Manasseh and Reuben did enlarge upon the Moabites and Ammonites. Here is promised a larger possession then ever they had before the captivity, and it doth no doubt point out the enlargement of the Church of Christ in the times of the Gospel, and particularly when Antichrist Typified in this Prophesie by Edom shall be destroyed; but we are to give the literal meaning, and think we do not miss of it.
