[174] And this account we give the reader, as it is contained in the commentaries of king Herod: but other historians do not agree with them, for they suppose that Herod did not find, but rather make, this an occasion for thus putting him to death, and that by treacherously laying a snare for him; for thus do they write: That Herod and he were once at a treat, and that Herod had given no occasion to suspect [that he was displeased at him], but put this question to Hyrcanus, Whether he had received any letters from Malchus? and when he answered that he had received letters, but those of salutation only; and when he asked further, whether he had not received any presents from him? and when he had replied that he had received no more than four horses to ride on, which Malchus had sent him; they pretended that Herod charged these upon him as the crimes of bribery and treason, and gave order that he should be led away and slain. And in order to demonstrate that he had been guilty of no offense, when he was thus brought to his end, they alleged how mild his temper had been, and that even in his youth he had never given any demonstration of boldness or rashness, and that the case was the same when he came to be king, but that he even then committed the management of the greatest part of public affairs to Antipater; and that he was now above fourscore years old, and knew that Herod's government was in a secure state. He also came over Euphrates, and left those who greatly honored him beyond that river, though he were to be entirely under Herod's government; and that it was a most incredible thing that he should enterprise any thing by way of innovation, and not at all agreeable to his temper, but that this was a plot of Herod's contrivance.
