[67] But now, as soon as that legion that had been at Emmaus was joined to Caesar at night, he removed thence, when it was day, and came to a place called Seopus; from whence the city began already to be seen, and a plain view might be taken of the great temple. Accordingly, this place, on the north quarter of the city, and joining thereto, was a plain, and very properly named Scopus, [the prospect,] and was no more than seven furlongs distant from it. And here it was that Titus ordered a camp to be fortified for two legions that were to be together; but ordered another camp to be fortified, at three furlongs farther distance behind them, for the fifth legion; for he thought that, by marching in the night, they might be tired, and might deserve to be covered from the enemy, and with less fear might fortify themselves; and as these were now beginning to build, the tenth legion, who came through Jericho, was already come to the place, where a certain party of armed men had formerly lain, to guard that pass into the city, and had been taken before by Vespasian. These legions had orders to encamp at the distance of six furlongs from Jerusalem, at the mount called the Mount of Olives ¹ which lies over against the city on the east side, and is parted from it by a deep valley, interposed between them, which is named Cedron.
