The Talmud, that vast treasury of speculation on divine things, had its origin about this period. Recent researches into that wilderness of thought reveal wonders and beauties that were never till recently divulged. The deepest insights, the most bewildering fancies, exist there side by side. The intellectual powers of a race exhausted themselves in efforts to penetrate the mysteries of faith. The fragments of national literature that had been rescued from oblivion, were pondered over, scrutinized, arranged, classified, with a superstitious veneration that would not be satisfied till all the possibilities of interpretation had been tried. The command to "search the scriptures" for in them were the words of eternal life, was accepted and faithfully obeyed. "The Talmud" says Emanuel Deutsch, "is more than a book of laws, it is a microcosm, embracing, even as does the Bible, heaven and earth. It is as if all the prose and poetry, the science, the faith and speculation of the old world were, though only in faint reflections, bound up in it _in nuce_." The theme of discussion, conjecture, speculation, allegory was, from first to last, the same,--the relation between Jehovah and his people, the nature and conditions of salvation, the purport of the law, the bearing of the promises. The entire field of investigation was open, reaching all the way from the number of words in the Bible to the secret of infinite being. No passage was left unexposed with all the keenness that faith aided by culture could supply; and when reason reached the end of its tether, fancy took up the work and threaded with unwearied industry the mazes of allegory. Among the problems that challenged solution was the one touching the Messiah, his attributes and offices, his nature and his kingdom. This theme had inexhaustible capacities and infinite attraction, for it was but another form of the theme of national deliverance which was uppermost in the Hebrew mind.
