Joash had been something of a weakling, as though the gloom of his early concealment in the Temple and the shadow of priestly dominance had paralysed his independence. Amaziah, on the other hand, born in the purple, was vigorous and restless. When he was secure upon the throne, and had done his duty to his father's memory, he bent his efforts to recover Edom. The Edomites had revolted in the days of his great-grandfather Jehoram,[277] and since then "did tear perpetually,"[278] harassing with incessant raids the miserable fellahîn of Southern Judah. They reaped the crops of the settled inhabitants, cut down their fruit-trees, burnt their farmsteads, and carried their children into cruel and hopeless slavery. One verse tells us all that the historian knew, or cared to relate, of Amaziah's campaign. He only says that it was eminently successful. Amaziah confronted the Edomites in the Valley of Salt,[279] on the border of Edom, to the south of the Dead Sea, and inflicted upon them a signal defeat. He not only slaughtered ten thousand of them, but, advancing southwards, he stormed and captured Selah or Petra, their rocky capital, two days' journey north of Ezion-Geber, on the gulf of Akabah.[280] Considering the natural strength of Petra, amid its mountain-fastnesses, this was a victory of which he might well be proud, and he marked his prowess by changing the name of the city to Joktheel, "subdued by God." The historian, copying the ancient record before him, says that Selah continued to be so called "to this day."[281] This is a curious instance of close transcription, for it is certain that Selah can only have retained the name of Joktheel for a very short period, and had lost it long before the days of the Exile. Even in the reign of Ahaz (B.C. 735-715) the Edomites had so completely recovered lost ground that they were able to make predatory excursions into Judah, and to threaten Hebron, which would have been obviously impossible if they were not masters of their own chief capital.[282] The district which Amaziah seems to have conquered was mainly west of the Arabah. He wished to restore Elath, and perhaps to carry out the old commerce with the Red Sea which Solomon began, and which had fired the ambition of Jehoshaphat. The conquest of Selah secured the road for his commercial caravans.
