[394] BY this time Herod had sailed out of Italy to Ptolemais, and had gotten together no small army, both of strangers and of his own countrymen, and marched through Galilee against Antignus. Silo also, and Ventidius, came and assisted him, being persuaded by Dellius, who was sent by Antony to assist in bringing back Herod. Now for Ventidius, he was employed in composing the disturbances that had been made in the cities by the means of the Parthians; and for Silo, he was in Judea indeed, but corrupted by Antigonus. However, as Herod went along his army increased every day, and all Galilee, with some small exception, joined him; but as he was to those that were in Masada, (for he was obliged to endeavor to save those that were in that fortress now they were besieged, because they were his relations,) Joppa was a hinderance to him, for it was necessary for him to take that place first, it being a city at variance with him, that no strong hold might be left in his enemies' hands behind him when he should go to Jerusalem. And when Silo made this a pretense for rising up from Jerusalem, and was thereupon pursued by the Jews, Herod fell upon them with a small body of men, and both put the Jews to flight and saved Silo, when he was very poorly able to defend himself; but when Herod had taken Joppa, he made haste to set free those of his family that were in Masada. Now of the people of the country, some joined him because of the friendship they had had with his father, and some because of the splendid appearance he made, and others by way of requital for the benefits they had received from both of them; but the greatest number came to him in hopes of getting somewhat from him afterward, if he were once firmly settled in the kingdom.
