When the whole earth rejoiceth - When the whole land shall rejoice in the restoration of the Jews, I will make thee desolate. Probably this refers to the time of the Maccabees.

Thus saith the Lord God, when the whole earth rejoiceth,.... When it shall go well with the world in general, and the inhabitants of it; when they shall enjoy great peace and prosperity. Jarchi has a very good note upon this clause,
"when I shall take my kingdom; for then the earth will rejoice, as it is said, the Lord reigns, let the earth rejoice;''
so when Christ takes to himself his great power, and reigns, his church and people will rejoice, Revelation 11:16, as well as at the destruction of antichrist, as follows:
I will make thee desolate; for so some render it, "the whole earth rejoiceth when I make thee desolate"; or, "so shall all the earth rejoice in the desolation which I shall make for thee" (c); see Revelation 18:20 and which agrees with what follows:
(c) "Sic laetabitur omnis terra in desolatione quam faciam tibi", Vatablus.

(Isaiah 65:13-14). "The whole earth" refers to Judea and the nations that submit themselves to Judea's God; when these rejoice, the foes of God and His people, represented by Edom as a nation, shall be desolate. Things shall be completely reversed; Israel, that now for a time mourns, shall then rejoice and for ever. Edom, that now rejoices over fallen Israel, shall then, when elsewhere all is joy, mourn, and for ever (Isaiah 65:17-19; Matthew 5:4; Luke 6:25). HAVERNICK loses this striking antithesis by translating, "According to the joy of the whole land (of Edom), so I will make thee desolate"; which would make Ezekiel 35:15 a mere repetition of this.

The whole earth - The inhabitants of all the countries round about thee. Rejoiceth - Is in peace and plenty.
