Adam Clarke on Deuteronomy 2:10

The Emims dwelt therein - Calmet supposes that these people were destroyed in the war made against them by Chedorlaomer and his allies, Gen 14:5. Lot possessed their country after the destruction of Sodom and Gomorrah. They are generally esteemed as giants; probably they were a hardy, fierce, and terrible people, who lived, like the wandering Arabs, on the plunder of others. This was sufficient to gain them the appellation of giants, or men of prodigious stature. See next verse, Deu 2:11 (note).
