He was by birth an Idumean, and one of the principal of that nation, on account of his ancestors and riches, and other authority to him belonging: he also persuaded Hyrcanus to fly to Aretas, the king of Arabia, and to lay claim to the kingdom; as also he persuaded Aretas to receive Hyrcanus, and to bring him back to his kingdom: he also cast great reproaches upon Aristobulus, as to his morals, and gave great commendations to Hyrcanus, and exhorted Aretas to receive him, and told him how becoming a filing it would be for him, who ruled so great a kingdom, to afford his assistance to such as are injured; alleging that Hyrcanus was treated unjustly, by being deprived of that dominion which belonged to him by the prerogative of his birth.

And when he had predisposed them both to do what he would have them, he took Hyrcanus by night, and ran away from the city, and, continuing his flight with great swiftness, he escaped to the place called Petra, which is the royal seat of the king of Arabia, where he put Hyrcanus into Aretas's hand; and by discoursing much with him, and gaining upon him with many presents, he prevailed with him to give him an army that might restore him to his kingdom.

This army consisted of fifty thousand footmen and horsemen, against which Aristobulus was not able to make resistance, but was deserted in his first onset, and was driven to Jerusalem; he also had been taken at first by force, if Scaurus, the Roman general, had not come and seasonably interposed himself, and raised the siege.

This Scaurus was sent into Syria from Armenia by Pompey the Great, when he fought against Tigranes; so Scaurus came to Damascus, which had been lately taken by Metellus and Lollius, and caused them to leave the place; and, upon his hearing how the affairs of Judea stood, he made haste thither as to a certain booty.

As soon, therefore, as he was come into the country, there came ambassadors from both the brothers, each of them desiring his assistance; but Aristobulus's three hundred talents had more weight with him than the justice of the cause; which sum, when Scaurus had received, he sent a herald to Hyrcanus and the Arabians, and threatened them with the resentment of the Romans and of Pompey, unless they would raise the siege.
