John Gill Commentary Jeremiah 25:21

"Edom, and Moab, and the children of Ammon;" — Jeremiah 25:21 (ASV)

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.
