[321] But Sanballat thought he had now gotten a proper opportunity to make his attempt, so he renounced Darius, and taking with him seven thousand of his own subjects, he came to Alexander; and finding him beginning the siege of Tyre, he said to him, that he delivered up to him these men, who came out of places under his dominion, and did gladly accept of him for his lord instead of Darius. So when Alexander had received him kindly, Sanballat thereupon took courage, and spake to him about his present affair. He told him that he had a son-in-law, Manasseh, who was brother to the high priest Jaddua; and that there were many others of his own nation, now with him, that were desirous to have a temple in the places subject to him; that it would be for the king's advantage to have the strength of the Jews divided into two parts, lest when the nation is of one mind, and united, upon any attempt for innovation, it prove troublesome to kings, as it had formerly proved to the kings of Assyria. Whereupon Alexander gave Sanballat leave so to do, who used the utmost diligence, and built the temple, and made Manasseh the priest, and deemed it a great reward that his daughter's children should have that dignity; but when the seven months of the siege of Tyre were over, and the two months of the siege of Gaza, Sanballat died. Now Alexander, when he had taken Gaza, made haste to go up to Jerusalem; and Jaddua the high priest, when he heard that, was in an agony, and under terror, as not knowing how he should meet the Macedonians, since the king was displeased at his foregoing disobedience. He therefore ordained that the people should make supplications, and should join with him in offering sacrifice to God, whom he besought to protect that nation, and to deliver them from the perils that were coming upon them; whereupon God warned him in a dream, which came upon him after he had offered sacrifice, that he should take courage, and adorn the city, and open the gates; that the rest should appear in white garments, but that he and the priests should meet the king in the habits proper to their order, without the dread of any ill consequences, which the providence of God would prevent. Upon which, when he rose from his sleep, he greatly rejoiced, and declared to all the warning he had received from God. According to which dream he acted entirely, and so waited for the coming of the king.
