Zarephath - Sarepta, a city of the Sidonians, 1 Kings 17:9. That is, they should possess the whole city of Phoenicia, called here that of the Canaanites.
Which is in Sepharad - This is a difficult word. Some think the Bosphorus is meant; others, Spain; others, France; others, the Euphrates; others, some district in Chaldea; for there was a city called Siphora, in Mesopotamia, above the division of the Euphrates. Dr. Lightfoot says it was a part of Edom. Those who were captives among the Canaanites should possess the country of the Canaanites; and those whom the Edomites had enslaved should possess the cities of their masters. See Newcome and Lowth.
And the captivity of this host of the children of Israel - , (it must, I believe, be rendered,) “which are among the Canaanites, as far as Zarephath, and the captivity of Jerusalem which is in Sepharad, shall possess the cities of the South.” Obadiah had described how the two tribes, whose were the promises to the house of David, should spread abroad on all sides. Here he represents how Judah should, in its turn, receive into its bosom those now carried away from them; so should all again be one fold.
Zarephath - (probably “smelting-house,” and so a place of slave-labor, pronounced Sarepta in Luke) Luke 4:26. belonged to Sidon 1 Kings 17:9, lying on the sea about halfway between it and Tyre.. These were then, probably, captives, placed by Tyrians for the time in safe keeping in the narrow plain between Lebanon and the sea, intercepted by Tyre itself from their home, and awaiting to be transported to a more distant slavery. These, with those already sold to the Grecians and in slavery at Sardis, formed one whole. They stand as representatives of all who, whatever their lot, had been rent off from the Lord‘s land, and had been outwardly severed from His heritage.
