4. At this behavior Pompey was angry; and taking with him that army which he was leading against the Nabateans, and the auxiliaries that came from Damascus, and the other parts of Syria, with the other Roman legions which he had with him, he made an expedition against Aristobulus; but as he passed by Pella and Scythopolis, he came to Corem, which is the first entrance into Judea when one passes over the midland countries, where he came to a most beautiful fortress that was built on the top of a mountain called Alexandrium, whither Aristobulus had fled; and thence Pompey sent his commands to him, that he should come to him. Accordingly, at the persuasions of many that he would not make war with the Romans, he came down; and when he had disputed with his brother about the right to the government, he went up again to the citadel, as Pompey gave him leave to do; and this he did two or three times, as flattering himself with the hopes of having the kingdom granted him; so that he still pretended he would obey Pompey in whatsoever he commanded, although at the same time he retired to his fortress, that he might not depress himself too low, and that he might be prepared for a war, in case it should prove as he feared, that Pompey would transfer the government to Hyrcanus. But when Pompey enjoined Aristobulus to deliver up the fortresses he held, and to send an injunction to their governors under his own hand for that purpose, for they had been forbidden to deliver them up upon any other commands, he submitted indeed to do so; but still he retired in displeasure to Jerusalem, and made preparation for war. A little after this, certain persons came out of Pontus, and informed Pompey, as he was on the way, and conducting his army against Aristobulus, that Mithridates was dead, and was slain by his son Pharmaces.
