34. The western extremities of Judæa towards Casius are occupied by Idumæans, and by the lake [Sirbonis]. The Idumæans are Nabatæans. When driven from their country[634] by sedition, they passed over to the Jews, and adopted their customs.[635] The greater part of the country along the coast to Jerusalem is occupied by the Lake Sirbonis, and by the tract contiguous to it; for Jerusalem is near the sea, which, as we have said,[636] may be seen from the arsenal of Joppa.[637] These districts (of Jerusalem and Joppa) lie towards the north; they are inhabited generally, and each place in particular, by mixed tribes of Egyptians, Arabians, and Phœnicians. Of this description are the inhabitants of Galilee, of the plain of Jericho, and of the territories of Philadelphia and Samaria,[638] surnamed Sebaste by Herod;[639] but although there is such a mixture of inhabitants, the report most credited, [one] among many things believed respecting the temple [and the inhabitants] of Jerusalem, is, that the Egyptians were the ancestors of the present Jews.[640] 35. An Egyptian priest named Moses, who possessed a portion of the country called the Lower [Egypt] * * * *, being dissatisfied with the established institutions there, left it and came to Judæa with a large body of people who worshipped the Divinity. He declared and taught that the Egyptians and Africans entertained erroneous sentiments, [CAS. 761] in representing the Divinity under the likeness of wild beasts and cattle of the field; that the Greeks also were in error in making images of their gods after the human form. For God [said he] may be this one thing which encompasses us all, land and sea, which we call heaven, or the universe, or the nature of things.[641] Who then of any understanding would venture to form an image of this Deity, resembling anything with which we are conversant? on the contrary, we ought not to carve any images, but to set apart some sacred ground and a shrine worthy of the Deity, and to worship Him without any similitude.[642] He taught that those who made fortunate dreams were to be permitted to sleep in the temple, where they might dream both for themselves and others; that those who practised temperance and justice, and none else, might expect good, or some gift or sign from the God, from time to time. 36. By such doctrine Moses[643] persuaded a large body of right-minded persons to accompany him to the place where Jerusalem now stands. He easily obtained possession of it, as the spot was not such as to excite jealousy, nor for which there could be any fierce contention; for it is rocky, and, although well supplied with water, it is surrounded by a barren and waterless territory.[644] The space within [the city] is 60 stadia [in circumference], with rock underneath the surface.
