EASTON’S BIBLE DICTIONARY (1897 EDITION)
Ashteroth Karnaim – Ashteroth of the two horns, the abode of the Rephaim (Gen. 14:5).
It may be identified with Ashtaroth preceding; called “Karnaim”, i.e., the “two-horned” (the crescent moon).
The Samaritan version renders the word by “Sunamein,” the present es-Sunamein, 28 miles south of Damascus.
