from Josephus' The Wars of The Jews

Book IV

Hebron...Now the people of the country say that it is an ancienter city, not only than any in that country, but than Memphis in Egypt, and accordingly its age is reckoned at two thousand and three hundred years. They also relate that it had been the habitation of Abram, the progenitor of the Jews, after he had removed out of Mesopotamia; and they say that his posterity descended from thence into Egypt, whose monuments are to this very time showed in that small city; the fabric of which monuments are of the most excellent marble, and wrought after the most elegant manner. There is also there showed, at the distance of six furlongs from the city, a very large turpentine tree (17) and the report goes, that this tree has continued ever since the creation of the world.

...Cerealis, one of his [Vespatian's]commanders, took a body of horsemen and footmen, and laid waste that part of Idumea which was called the Upper Idumea, and attacked Caphethra, which pretended to be a small city, and took it at the first onset, and burnt it down. He also attacked Caphatabira...When Cerealis had conquered them, he went to Hebron, another very ancient city. I have told you already that this city is situated in a mountainous country not far off Jerusalem; and when he had broken into the city by force, what multitude and young men were left therein he slew, and burnt down the city; so that as now all the places were taken, excepting Herodlum, and Masada, and Macherus, which were in the possession of the robbers, so Jerusalem was what the Romans at present aimed at.
