שִׂ֤ישִׂי וְשִׂמְחִי֙ בַּת־אֱד֔וֹם יושבתי [יוֹשֶׁ֖בֶת] בְּאֶ֣רֶץ ע֑וּץ גַּם־עָלַ֙יִךְ֙ תַּעֲבָר־כּ֔וֹס תִּשְׁכְּרִ֖י וְתִתְעָרִֽי׃ (ס)
Bersukarialah dan bergembiralah, hai putri Edom, yang tinggal di negeri Us! Cawan itu akan sampai juga kepadamu; engkau akan mabuk dan muntah-muntah.
Tze'enah Ure'enah
“Rejoice” [4:21]. Rejoice you Edom for a short time. You will also drink a bitter drink and will slobber over yourself from great troubles.
Rashi
Rejoice in gladness city of Edom. Yirmiyahu prophesied about the destruction of the second Beis Hamikdosh which the Romans would destroy.29Alternatively, it refers to Edom who rejoiced at the downfall of Yerusholayim and rejoiced at the destruction of the first Beis Hamikdosh, as it says “Remember, Adonoy, for the offspring of Edom...who say ‘Destroy! Destroy!’ etc., in Tehilim 137:7.
Rashi
Rejoice in gladness. For the time being, but ultimately, the cup of retribution will pass also over you, and you will become drunk from it.
Rashi
[Till] you vomit. And you will throw up, as in, “and she emptied וַתְּעַר her pitcher.”30Bereishis 24:20.
