[213] But Simon, who was made high priest by the multitude, on the very first year of his high priesthood set his people free from their slavery under the Macedonians, and permitted them to pay tribute to them no longer; which liberty and freedom from tribute they obtained after a hundred and seventy years ¹ of the kingdom of the Assyrians, which was after Seleucus, who was called Nicator, got the dominion over Syria. Now the affection of the multitude towards Simon was so great, that in their contracts one with another, and in their public records, they wrote, "in the first year of Simon the benefactor and ethnarch of the Jews;" for under him they were very happy, and overcame the enemies that were round about them; for Simon overthrew the city Gazara, and Joppa, and Jamhis. He also took the citadel of Jerusalem by siege, and cast it down to the ground, that it might not be any more a place of refuge to their enemies when they took it, to do them a mischief, as it had been till now. And when he had done this, he thought it their best way, and most for their advantage, to level the very mountain itself upon which the citadel happened to stand, that so the temple might be higher than it. And indeed, when he had called the multitude to an assembly, he persuaded them to have it so demolished, and this by putting them in mind what miseries they had suffered by its garrison and the Jewish deserters, and what miseries they might hereafter suffer in case any foreigner should obtain the kingdom, and put a garrison into that citadel. This speech induced the multitude to a compliance, because he exhorted them to do nothing but what was for their own good: so they all set themselves to the work, and leveled the mountain, and in that work spent both day and night without any intermission, which cost them three whole years before it was removed, and brought to an entire level with the plain of the rest of the city. After which the temple was the highest of all the buildings, now the citadel, as well as the mountain whereon it stood, were demolished. And these actions were thus performed under Simon.
