(Isaiah 36:19; Isaiah 37:13) or Ar'phad (Heb. Arpad', אִרְפָּד, perhaps a support; but see below; Sept. in 2 Kings Ἀρφάδ, elsewhere Ἀρφάθ , in Isaiah 10:9 undistinguishable), a Syrian city, having its own king (2 Kings 19:13; Isaiah 37:13), in the neighborhood of Hamath (2 Kings 18:34; Isaiah 10:9; Isaiah 36:19) and Damascus (Jeremiah 49:23), with both of which it appears to have been conquered by the Assyrians under Sennacherib. Michaelis and others seek Arphad in Raphance or Raphanee of the Greek geographers (Ptol. v, 15; Steph. Byzant. in Ε᾿πιφάνεια; Joseph. War, 7:1, 3; 7:5, 1), which was a day's journey west of Hamath (Mannert, VI, i, 431). Paulus (Comment. in Isaiah 10:9) thinks it was a city in the neighborhood of the Tigris and Euphrates. Some, however, are content to find this Arphad in the A rpha (Ἀρφᾶ ) which Josephus (War, iii, 3, 5) mentions as situated on the north-eastern frontier of the northernmost province of Herod Agrippa's tetrarchy; also called A rtha (Ἀρθᾶ ) or Arfa by other ancient writers (Reland, Palcest. p. 584). But it seems best (with Doderloin and others) to refer it to the Phoenician island city Arvad or Aradus (q.v.), which was opposite Hamath (the interchange of פ and ו being very natural).
