[80] BUT now came another accusation from the Jews against Archelaus at Rome, which he was to answer to. It was made by those ambassadors who, before the revolt, had come, by Varus's permission, to plead for the liberty of their country; those that came were fifty in number, but there were more than eight thousand of the Jews at Rome who supported them. And when Caesar had assembled a council of the principal Romans in Apollo's ¹ temple, that was in the palace, (this was what he had himself built and adorned, at a vast expense,) the multitude of the Jews stood with the ambassadors, and on the other side stood Archelaus, with his friends; but as for the kindred of Archelaus, they stood on neither side; for to stand on Archelaus's side, their hatred to him, and envy at him, would not give them leave, while yet they were afraid to be seen by Caesar with his accusers. Besides these, there were present Archelaus's brother Philip, being sent thither beforehand, out of kindness by Varus, for two reasons: the one was this, that he might be assisting to Archelaus; and the other was this, that in case Caesar should make a distribution of what Herod possessed among his posterity, he might obtain some share of it.
