Because thou hast said: The two nations, and the two lands shall be mine, and I will possess them by inheritance: whereas the Lord was there.

Because of thy saying: The two nations and the two lands are mine, and we have possessed it, And Jehovah hath been there;

Because you have said, The two nations and the two countries are to be mine, and we will take them for our heritage; though the Lord was there:

For you have said, 'Two nations and two lands will be mine, and I will possess them as an inheritance,' though the Lord was in that place.

These two nations - Israel and Judah.

These two nations - Israel and Judah. The Idumeans thought of conquering and possessing both; and they would have succeeded, but only the Lord was there; and this spoiled their projects, and blasted their hopes.

Because thou hast said, (e) These two nations and these two countries shall be mine, and we will possess it; though the LORD was (f) there:
(e) Meaning, Israel and Judah.
(f) And so by fighting against God's people they should go about to put him out of his own possession.

Because thou hast said, these two nations and these two countries shall be mine, and we will possess it,.... Meaning either Idumea he was now possessed of, and Israel he hoped to be, upon the people of it being carried captive; or rather the two nations of Israel and Judah, and their countries; which he pleased himself with would fall into his hands, as next heir to them; the posterity of his brother being dispossessed of them. This may denote the claim that Rome makes upon each of the Protestant nations and countries; and which she will think all her own, and that she is in the possession of them, upon the slaying of the witnesses; and when she will say, "I sit a queen, and am no widow", Revelation 18:7.
Whereas the Lord was there; and heard their words, as Kimchi; and knew their thoughts, as Jarchi; so the Targum,
"and before the Lord the thoughts of the heart were manifest.''
The land of Judea was Immanuel's land; and as the Lord had been in it, and granted his gracious presence in the tabernacle and temple, so he still continued his powerful presence in it, to protect and keep it for his people; who should return to it after their captivity, and inhabit it until the Messiah came, who was to be born in it. Or it may be rendered, "though the Lord was" or "dwelt there" (x); denoting the great impiety and daring wickedness of the Edomites, to think and talk of possessing a country that was the Lord's, and where he was: and this holds good of the true reformed churches of Christ; the Lord is there, and therefore, though they may be brought very low, and antichrist may triumph over them, and imagine he has got them under his power again, where they shall continue; yet on a sudden his destruction will come, and their deliverance. Or, "where the Lord was" (y); but he has now departed, and will never return more, the temple being destroyed; so they said, encouraging themselves.
(x) "licet Dominus ibi habitaverit", Piscator. So Syr. (y) "Ubi Jehovah fuit", Junius & Tremellius, Polanus; "et Jehovah ibi fuit", Starckius.

When we see the vanity of the world in the disappointments, losses, and crosses, which others meet with, instead of showing ourselves greedy of worldly things, we should sit more loose to them. In the multitude of words, not one is unknown to God; not the most idle word; and the most daring is not above his rebuke. In the destruction of the enemies of the church, God designs his own glory; and we may be sure that he will not come short of his design. And when the fulness of the Jews and Gentiles shall come into the church, all antichristian opposers shall be destroyed.

So far from being allowed to enter on Israel's vacated inheritance, as Edom hoped (Ezekiel 36:5; Psalm 83:4, Psalm 83:12; Obadiah 1:13), it shall be that he shall be deprived of his own; and whereas Israel's humiliation was temporary, Edom's shall be perpetual.
Lord was there-- (Ezekiel 48:35; Psalm 48:1, Psalm 48:3; Psalm 132:13-14). Jehovah claimed Judea as His own, even when the Chaldeans had overthrown the state; they could not remove Him, as they did the idols of heathen lands. The broken sentences express the excited feelings of the prophet at Edom's wicked presumption. The transition from the "two nations and two countries" to "it" marks that the two are regarded as one whole. The last clause, "and Jehovah was there," bursts in, like a flash of lightning, reproving the wicked presumption of Edom's thought.

Though - Though God was with Israel.
