When the whole earth rejoiceth, I will make thee desolate. By "the whole earth," Fairbairn, Haverniek, and Schroder understand "the whole land of Edom." In this ease the sense is that, as the whole land of Edom had previously exulted with joy, so should it in the future be made completely desolate.
Ewald, Hengstenberg, Keil, Kliefoth, Smend, and Plumptre, however, more correctly interpret the phrase as signifying the whole human race, with the exception of Edom. Accordingly, the thought seems to be, not that of Ewald and Smend, that Jehovah would make Edom's devastation a sport or comedy (freudespiel) to the whole world; or that of Kliefoth and Hitzig, that God would make Edom desolate, whilst all the earth rejoiced over her downfall; but that of Keil, Plumptre, and others, that just as Jehovah was preparing for the whole earth of redeemed humanity a glorious future of joy, so certainly would Edom and all whom Edom represented be excluded from participation in that joy.
