כִּֽי־אֲנִ֞י חָשַׂ֣פְתִּי אֶת־עֵשָׂ֗ו גִּלֵּ֙יתִי֙ אֶת־מִסְתָּרָ֔יו וְנֶחְבָּ֖ה לֹ֣א יוּכָ֑ל שֻׁדַּ֥ד זַרְע֛וֹ וְאֶחָ֥יו וּשְׁכֵנָ֖יו וְאֵינֶֽנּוּ׃
Я обнажил Исава, раскрыл его тайные места, и он не сможет спрятаться; Семя его испорчено, и братья его, и соседи его, а его нет.
Abarbanel
And the explanation of the pasuk "It has been heard from Hashem..." The Radak says that this is OVadiah saying "myself and the other prophets who discuss the destructions of Edom..." thus says Hashem... as if an envoy has een sent out among the nations to publicize this so that all the nations will come to war against the land of Edom. And if htis is the first thing that Ovadiah says why does it say AND an envoy has been sent out like it's connecting to the earlier and that's not the only questoin. Also how is it possible that all the nations of the world will rise up wihtout a reason to fight against Edom and what is this envoy that was sent and who sent it? Rather the true meaning is waht I said two times that the nation of Edom is the summation of the Christians that begin with the Romans will be awoken to go up and conquer Jerusalem because it is holy for their religion and Jesu is buried there as well and just like they have many times been stirred to conqured for any given reason. And because today all of Eretz Yisrael is under the rule of Egypt, they will therefore first fight the Christians in Egypt and deal a formidable blow and aftewrards conquer the land. And this the tidings that are heard among the nations that are east and south that are mostly the Muslims who will hear that the Christians brought their legions from their land and destroyed Egypt and conqured Israel and Jerusalem and it is a holy land for the Muslims as well. And then the Muslims will be stirred from the east to the south and they will each say to their fellow let us go up and fight in the name of our Gd against the accursed Christians and take vengeance from them for our Egyptian brothers since they have spilt their blood like water and take back the holy land from their hands. This is the envoy among the nations. And thus said Jeremiah (49:10) the envoy has been sent to gather and come against it and come to war...the meaning of this is the message and rumeors will be spread among the lands of the Muslims about waht the Christians have done in Egypt and the holy land when they have come for battle.
