5. bar of Damascus--that is, the bar of its gates (compare Jer 51:30).
      the inhabitant--singular for plural, "inhabitants." HENDERSON, because of the parallel, "him that holdeth the scepter," translates, "the ruler." But the parallelism is that of one clause complementing the other, "the inhabitant" or subject here answering to "him that holdeth the scepter" or ruler there, both ruler and subject alike being cut off.
      Aven--the same as Oon or Un, a delightful valley, four hours' journey from Damascus, towards the desert. Proverbial in the East as a place of delight [JOSEPHUS ABASSUS]. It is here parallel to "Eden," which also means "pleasantness"; situated at Lebanon. As JOSEPHUS ABASSUS is a doubtful authority, perhaps the reference may be rather to the valley between Lebanon and Anti-Lebanon, called El-Bekaa, where are the ruins of the Baal-bek temple of the sun; so the Septuagint renders it On, the same name as the city in Egypt bears, dedicated to the sun-worship (Ge 41:45; Heliopolis, "the city of the sun," Eze 30:17, Margin). It is termed by Amos "the valley of Aven," or "vanity," from the worship of idols in it.
      Kir--a region subject to Assyria (Isa 22:6) in Iberia, the same as that called now in Armenian Kur, lying by the riverCyrus which empties itself into the Caspian Sea. Tiglath-pileser fulfilled this prophecy when Ahaz applied for help to him against Rezin king of Syria, and the Assyrian king took Damascus, slew Rezin, and carried away its people captive to Kir.
