The same words are ever to be repeated, that Jeremiah made all these nations to drink the cup. He mentions the Idumeans, the posterity of Esau, and also the Moabites, the descendants of Lot, as also were the Ammonites There was a relationship between these three nations and the Israelites; hence the Prophet seems designedly to have connected these three nations together. He adds --

(q) Edom, and Moab, and the children of Ammon,
(q) Edom is here taken for the whole country and Uz for a part of it.

Edom, and Moab, and the children of Ammon. All well known and implacable enemies of Israel. The Edomites descended from Esau; and the Moabites and Ammonites from Moab and Ammon, the two sons of Lot by his daughters. Their destruction is prophesied of in the forty eighth and forty ninth chapters.

Edom . . . Moab . . . Ammon--joined together, as being related to Israel (see Jeremiah. 48:1-49:39).
