[422] After this, when the queen was fallen into a dangerous distemper, Aristobulus resolved to attempt the seizing of the government; so he stole away secretly by night, with only one of his servants, and went to the fortresses, wherein his friends, that were such from the days of his father, were settled; for as he had been a great while displeased at his mother's conduct, so he was now much more afraid, lest, upon her death, their whole family should be under the power of the Pharisees; for he saw the inability of his brother, who was to succeed in the government; nor was any one conscious of what he was doing but only his wife, whom he left at Jerusalem with their children. He first of all came to Agaba, where was Galestes, one of the potent men before mentioned, and was received by him. When it was day, the queen perceived that Aristobulus was fled; and for some time she supposed that his departure was not in order to make any innovation; but when messengers came one after another with the news that he had secured the first place, the second place, and all the places, for as soon as one had begun they all submitted to his disposal, then it was that the queen and the nation were in the greatest disorder, for they were aware that it would not be long ere Aristobulus would be able to settle himself firmly in the government. What they were principally afraid of was this, that he would inflict punishment upon them for the mad treatment his house had had from them. So they resolved to take his wife and children into custody, and keep them in the fortress that was over the temple. ¹ Now there was a mighty conflux of people that came to Aristobulus from all parts, insomuch that he had a kind of royal attendants about him; for in a little more than fifteen days he got twenty-two strong places, which gave him the opportunity of raising an army from Libanus and Trachonitis, and the monarchs; for men are easily led by the greater number, and easily submit to them. And besides this, that by affording him their assistance, when he could not expect it, they, as well as he, should have the advantages that would come by his being king, because they had been the occasion of his gaining the kingdom. Now the eiders of the Jews, and Hyrcanus with them, went in unto the queen, and desired that she would give them her sentiments about the present posture of affairs, for that Aristobulus was in effect lord of almost all the kingdom, by possessing of so many strong holds, and that it was absurd for them to take any counsel by themselves, how ill soever she were, whilst she was alive, and that the danger would be upon them in no long time. But she bid them do what they thought proper to be done; that they had many circumstances in their favor still remaining, a nation in good heart, an army, and money in their several treasuries; for that she had small concern about public affairs now, when the strength of her body already failed her.
