חֲז֖וֹן עֹֽבַדְיָ֑ה כֹּֽה־אָמַר֩ אֲדֹנָ֨י יְהוִ֜ה לֶאֱד֗וֹם שְׁמוּעָ֨ה שָׁמַ֜עְנוּ מֵאֵ֤ת יְהוָה֙ וְצִיר֙ בַּגּוֹיִ֣ם שֻׁלָּ֔ח ק֛וּמוּ וְנָק֥וּמָה עָלֶיהָ לַמִּלְחָמָֽה׃
Penglihatan Obaja. Beginilah firman Tuhan Yang Mahakekal tentang Edom: Kami telah mendengar kabar dari Yang Mahakekal, dan seorang utusan telah dikirim ke tengah bangsa-bangsa: “Bangkitlah, marilah kita bangkit melawan dia untuk berperang!”
Rashi
The vision of Obadiah—Why is Obadiah different that he was chosen to prophesy concerning Edom and did not prophesy any other prophecy? Our Sages of blessed memory stated: Obadiah was an Edomite proselyte. Said the Holy One, blessed be He: From them and in them will I bring upon them. Let Obadiah, who dwelt between two wicked people, Ahab and Jezebel, and did not learn from their deeds, come and impose retribution upon Esau, who dwelt between two righteous people, Isaac and Rebecca, and did not learn from their deeds. [from Sanhedrin 39b]
Abarbanel
The words of the prophet Ovadiah are one single prophecy only, therefore I haven't divided it into separate prophecies. And on it I have six questions.
Abarbanel
The first question is whether this prophecy that Ovadiah said about Edom was already fulfilled by Nevuchadnezer after he conquered Eretz Yisrael and destroyed Jerusalem, he then subjugated the kingdoms of the nations surrounding including Egypt, Amon, Moav, Edom and the other nations as it says in the book of Jeremiah. Alternatively, was this prophecy fulfilled afterwards in the days of Hyrcanus, the Hasmonean king who went to the land of Edom and struck Edom and subjugated its pride and made them work and pay taxes and made them do bris milah like it's told in the works of Yosef Ben Gurion. Or, rather, this is a prophecy that hasn't yet been fulfilled and will be in the future.
