[356] So when Alexander was delivered from the fear he was in of Ptolemy, he presently made an expedition against Coelesyria. He also took Gadara, after a siege of ten months. He took also Areathus, a very strong fortress belonging to the inhabitants above Jordan, where Theodorus, the son of Zeno, had his chief treasure, and what he esteemed most precious. This Zeno fell unexpectedly upon the Jews, and slew ten thousand of them, and seized upon Alexander's baggage. Yet did not this misfortune terrify Alexander; but he made an expedition upon the maritime parts of the country, Raphia and Anthedon, (the name of which king Herod afterwards changed to Agrippias,) and took even that by force. But when Alexander saw that Ptolemy was retired from Gaza to Cyprus, and his mother Cleopatra was returned to Egypt, he grew angry at the people of Gaza, because they had invited Ptolemy to assist them, and besieged their city, and ravaged their country. But as Apollodotus, the general of the army of Gaza, fell upon the camp of the Jews by night, with two thousand foreign and ten thousand of his own forces, while the night lasted, those of Gaza prevailed, because the enemy was made to believe that it was Ptolemy who attacked them; but when day was come on, and that mistake was corrected, and the Jews knew the truth of the matter, they came back again, and fell upon those of Gaza, and slew of them about a thousand. But as those of Gaza stoutly resisted them, and would not yield for either their want of any thing, nor for the great multitude that were slain, (for they would rather suffer any hardship whatever than come under the power of their enemies,) Aretas, king of the Arabians, a person then very illustrious, encouraged them to go on with alacrity, and promised them that he would come to their assistance; but it happened that before he came Apollodotus was slain; for his brother Lysimachus envying him for the great reputation he had gained among the citizens, slew him, and got the army together, and delivered up the city to Alexander, who, when he came in at first, lay quiet, but afterward set his army upon the inhabitants of Gaza, and gave them leave to punish them; so some went one way, and some went another, and slew the inhabitants of Gaza; yet were not they of cowardly hearts, but opposed those that came to slay them, and slew as many of the Jews; and some of them, when they saw themselves deserted, burnt their own houses, that the enemy might get none of their spoils; nay, some of them, with their own hands, slew their children and their wives, having no other way but this of avoiding slavery for them; but the senators, who were in all five hundred, fled to Apollo's temple, (for this attack happened to be made as they were sitting,) whom Alexander slew; and when he had utterly overthrown their city, he returned to Jerusalem, having spent a year in that siege.
