Hadrach

the name of a country (Zech 9:1) which cannot be identified. Rawlinson would identify it with Edessa. He mentions that in the Assyrian inscriptions it is recorded that "Shalmanezer III. made two expeditions, the first against Damascus B.C. 773, and the second against Hadrach B.C. 772; and again that Asshurdanin-il II. made expeditions against Hadrach in B.C. 765 and 755."
