John Wesley on Jeremiah 49:7

Edom - The Edomites were the posterity of Esau the eldest son of Isaac, but disinherited; the blessing being given to his younger brother Jacob, who was head of the twelve tribes of Israel. God promised him that he should have a fat, and plentiful country, tho' his brother should be his lord; and foretold, that he should break his brother's yoke from off his neck: the land of Seir was his country. The Edomites coasted southward upon Canaan, the Israelites passed by their coasts to go into Canaan, their way lay thro' Edom, but their king refusing to suffer them to go through, God ordered them to go another way. Balaam prophesied their ruin. They were enemies to the Israelites in the time of Saul, 1Sam 14:47, and David, 2Sam 8:14, and Amaziah, 2Kings 14:17, who slew of them ten thousand, and took Selah, calling it Jokteel. Many of the prophets foretold their ruin, Jeremiah in this place, Ezek 25:12 - 14 Joel 3:19 Amos 9:11,12, and others. Teman - Was a city of Edom.
