Obadiah 1:16 - Matthew Poole's English Annotations on the Holy Bible

This, with some, is a confirmation of what is threatened against Edom, yet others make this verse the beginning of the consolatory sermon to Judah, and either suits well with the context. As ye, O Edomites, or ye, O Jews. Have drunk: if you interpret this drinking as feasting, revelling, and carousing, it is to be applied to the Edomites and others, who triumphed first by their arms, next in their cups, over conquered Judah. Upon my holy mountain; either the whole land, or Jerusalem, or the temple, for all these are called by this name; and here these proud and insolent conquerors did drink confusion to the Jews. All the heathen; the nations, enemies to Edom, shall on Mount Esau conquer first, and then triumph in their revelling feasts, and drink continually, till they have swallowed up Edom. And they, Edomites, shall be as though they had not been; shall by this means perish utterly, and their memory cease with them; so it suits with Ezekiel 35:14,15, which see. Others refer the words to the Jews, thus: Ye have drunk the cup of astonishment in your land, and in Jerusalem, my holy mountain; so now ere long the nations which afflicted you shall drink of the cup of astonishment long, yea, drink the dregs of it, so that they shall perish, and be no more, when your day of dark affliction shall end in a day of light and salvation; and when other nations do this, Edom shall much more, because most deeply guilty above others see Jeremiah 49:17,18,21,22.
