Ruins at Tell el-Kheleifeh were identified with Ezion-Geber by the German explorer F. Frank and later excavated by Nelson Glueck, who thought he had confirmed the identification, but a later re-evaluation dates them to a period between the 8th and 6th centuries BCE with occupation continuing possibly into the 4th century BCE.Pratico, Gary D.
