Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
Cave-men, a race of Troglodytes who dwelt in the limestone caves which abounded in Edom. Their ancestor was "Seir," who probably gave his name to the district where he lived. They were a branch of the Hivites (Gen. 14:6, 36:20-30; 1 Chr. 1:38, 39). They were dispossessed by the descendants of Esau, and as a people gradually became extinct (Dt. 2:12-22).
