[349] Hereupon Zenodorus was grieved, in the first place, because his principality was taken away from him; and still more so, because he envied Herod, who had gotten it; So he went up to Rome to accuse him, but returned back again without success. Now Agrippa was [about this time] sent to succeed Caesar in the government of the countries beyond the Ionian Sea, upon whom Herod lighted when he was wintering about Mitylene, for he had been his particular friend and companion, and then returned into Judea again. However, some of the Gadarens came to Agrippa, and accused Herod, whom he sent back bound to the king without giving them the hearing. But still the Arabians, who of old bare ill-will to Herod's government, were nettled, and at that time attempted to raise a sedition in his dominions, and, as they thought, upon a more justifiable occasion; for Zenodorus, despairing already of success as to his own affairs, prevented [his enemies], by selling to those Arabians a part of his principality, called Auranitis, for the value of fifty talents; but as this was included in the donations of Caesar, they contested the point with Herod, as unjustly deprived of what they had bought. Sometimes they did this by making incursions upon him, and sometimes by attempting force against him, and sometimes by going to law with him. Moreover, they persuaded the poorer soldiers to help them, and were troublesome to him, out of a constant hope that they should reduce the people to raise a sedition; in which designs those that are in the most miserable circumstances of life are still the most earnest; and although Herod had been a great while apprized of these attempts, yet did not he indulge any severity to them, but by rational methods aimed to mitigate things, as not willing to give any handle for tumults.
