[101] And while not the king only, but the philosopher Menedemus also, admired them, and said that all things were governed by Providence, and that it was probable that thence it was that such force or beauty was discovered in these men's words, they then left off asking any more such questions. But the king said that he had gained very great advantages by their coming, for that he had received this profit from them, that he had learned how he ought to rule his subjects. And he gave order that they should have every one three talents given them, and that those that were to conduct them to their lodging should do it. Accordingly, when three days were over, Demetrius took them, and went over the causeway seven furlongs long: it was a bank in the sea to an island. And when they had gone over the bridge, he proceeded to the northern parts, and showed them where they should meet, which was in a house that was built near the shore, and was a quiet place, and fit for their discoursing together about their work. When he had brought them thither, he entreated them (now they had all things about them which they wanted for the interpretation of their law) that they would suffer nothing to interrupt them in their work. Accordingly, they made an accurate interpretation, with great zeal and great pains, and this they continued to do till the ninth hour of the day; after which time they relaxed, and took care of their body, while their food was provided for them in great plenty: besides, Dorotheus, at the king's command, brought them a great deal of what was provided for the king himself. But in the morning they came to the court and saluted Ptolemy, and then went away to their former place, where, when they had washed their hands, ¹ and purified themselves, they betook themselves to the interpretation of the laws. Now when the law was transcribed, and the labor of interpretation was over, which came to its conclusion in seventy-two days, Demetrius gathered all the Jews together to the place where the laws were translated, and where the interpreters were, and read them over. The multitude did also approve of those elders that were the interpreters of the law. They withal commended Demetrius for his proposal, as the inventor of what was greatly for their happiness; and they desired that he would give leave to their rulers also to read the law. Moreover, they all, both the priest and the ancientest of the elders, and the principal men of their commonwealth, made it their request, that since the interpretation was happily finished, it might continue in the state it now was, and might not be altered. And when they all commended that determination of theirs, they enjoined, that if any one observed either any thing superfluous, or any thing omitted, that he would take a view of it again, and have it laid before them, and corrected; which was a wise action of theirs, that when the thing was judged to have been well done, it might continue for ever.
