Matthew Poole and continuators on Lamentations 4:21

21 Rejoyce and be glad, O daughter of Edom, that dwellest in the land of Uz , the cup also shall pass through unto thee : thou shalt be drunken and shalt make thy self naked .

The Edomites were descended from Esau the Elder Brother of Iacob, and dwelled in a part of Arabia that obtained the name of Vz, probably from Vz the son of Dishan who descended from Seir, Gen. 36.20 28. they out of their old hatred to the Jews rejoyced at their ruine, as we learn from the Prophesie of Obadiah, who upon this account was sent to prophesie against them, the Prophet here ironically saith Rejoyce in the same sense as Eccles. 11.9. Solomon bids the young man rejoyce, but their joy should be but for a little time.

For God was dealing out the cup of his fury to more then the Jewish Nation, and amongst others to the Edomites.

And they should be filled, and intoxicated with it, and make themselves naked as drunken men sometimes do in their debauches.
