Nearly three hundred years after Jehoshaphat, and nearly five hundred years after David, the young King Josiah was reigning in Jerusalem. The temple had fallen into ruin, and the good king determined to have it repaired. Hilkiah, the high priest, who was rummaging among the rubbish of the dilapidated sanctuary, found there the Book of the Law of the Lord. The surprise which he manifests at this discovery, the trepidation of Shaphan the scribe, who hastens to tell the king about it, and the consternation of the king when he listens for the first time in his life to the reading of the book, and discovers how grievously its commandments have been disobeyed, form one of the most striking scenes of the old history. "How are we to explain," asks Dr. Perowne, "this surprise and alarm in the mind of Josiah, betraying, as it does, such utter ignorance of the Book of the Law and the severity of its threatenings,--except on the supposition that as a written document it had well-nigh perished?" [Footnote: Smith's _Bible Dictionary_, art. "Pentateuch."] Undoubtedly "the Book of the Law" thus discovered was that body of legislation which lies at the heart of the Deuteronomic code; and this was never again lost sight of by the Jewish people. It was less than fifty years after this that Nebuchadnezzar destroyed the city and the temple and carried the people away into captivity. And it was not until their return from the Captivity, seventy years later, that these sacred writings began to assume that place of eminence in the religious system of the Jews which they have held in later times. The man by whom the Jews were taught to cherish and study these writings was Ezra, one of the returning exiles. This Ezra, the record says, "was a ready scribe in the law of Moses which the Lord God of Israel had given," and "he had prepared his heart to seek the law of the Lord, and to do it and to teach in Israel statutes and judgments." He it was, no doubt, who gave to these laws their last revision, and who put the Pentateuch substantially into the shape in which we have it now. Doubtless much was added at this time; ritual rules which had been handed down orally were written out and made part of the code; the Pentateuch, after the Exile, was a more elaborate law book than that which Hilkiah found in the old temple. Under the presidency of Ezra in Jerusalem, and in the days which followed, the Book of the Law was exalted; it was the standard of authority; it was read in the temple and explained in the synagogues; its writings were woven into all the thought and life of the people of Israel; there never has been a time since that day when the history of the reign of any king could have been written without mentioning the law of Moses; there never has been a decade when any adequate account of the life of the Jewish people could have been given which would not bring this book constantly into view.
