Nor was it merely purity of descent of which the Eastern dispersion could boast. In truth, Palestine owed everything to Ezra, the Babylonian, [51] a man so distinguished that, according to tradition, the Law would have been given by him, if Moses had not previously obtained that honor. Putting aside the various traditional ordinances which the Talmud ascribes to him, [52] we know from the Scriptures what his activity for good had been. Altered circumstances had brought many changes to the new Jewish State. Even the language, spoken and written, was other than formerly. Instead of the characters anciently employed, the exiles brought with them, on their return, those now common, the so-called square Hebrew letters, which gradually came into general use. [53] [54] The language spoken by the Jews was no longer Hebrew, but Aramæan, both in Palestine and in Babylonia; [55] in the former the Western, in the latter the Eastern dialect. In fact, the common people were ignorant of pure Hebrew, which henceforth became the language of students and of the Synagogue. Even there a Methurgeman, or interpreter, had to be employed to translate into the vernacular the portions of Scripture read in the public services, [56] and the addresses delivered by the Rabbis. This was the origin of the so-called Targumim, or paraphrases of Scripture. In earliest times, indeed, it was forbidden to the Methurgeman to read his translation or to write down a Targum, lest the paraphrase should be regarded as of equal authority with the original. It was said that, when Jonathan brought out his Targum on the Prophets, a voice from heaven was heard to utter: Who is this that has revealed My secrets to men?' [57] Still, such Targumim seem to have existed from a very early period, and, amid the varying and often incorrect renderings, their necessity must have made itself increasingly felt. Accordingly, their use was authoritatively sanctioned before the end of the second century after Christ. This is the origin of our two oldest extant Targumim: that of Onkelos (as it is called), on the Pentateuch; and that on the Prophets, attributed to Jonathan the son of Uzziel. These names do not, indeed, accurately represent the authorship of the oldest Targumim, which may more correctly be regarded as later and authoritative recensions of what, in some form, had existed before. But although these works had their origin in Palestine, it is noteworthy that, in the form in which at present we possess them, they are the outcome of the schools of Babylon.
But Palestine owed, if possible, a still greater debt to Babylonia. The new circumstances in which the Jews were placed on their return seemed to render necessary an adaptation of the Mosaic Law, if not new legislation. Besides, piety and zeal now attached themselves to the outward observance and study of the letter of the Law. This is the origin of the Mishnah, or Second Law, which was intended to explain and supplement the first. This constituted the only Jewish dogmatics, in the real sense, in the study of which the sage, Rabbi, scholar, scribe, and Darshan, [58] were engaged. The result of it was the Midrash, or investigation, a term which afterwards was popularly applied to commentaries on the Scriptures and preaching. From the outset, Jewish theology divided into two branches: the Halakhah and the Haggadah. The former (from halakh, to go) was, so to speak, the Rule of the Spiritual Road, and, when fixed, had even greater authority than the Scriptures of the Old Testament, since it explained and applied them. On the other hand, the Haggadah [59] (from nagad, to tell) was only the personal saying of the teacher, more or less valuable according to his learning and popularity, or the authorities which he could quote in his support. Unlike the Halakhah, the Haggadah had no absolute authority, either as to doctrine practice, or exegesis. But all the greater would be its popular influence, [60] and all the more dangerous the doctrinal license which it allowed. In fact, strange as it may sound, almost all the doctrinal teaching of the Synagogue is to be derived from the Haggadah - and this also is characteristic of Jewish traditionalism. But, alike in Halakhah and Haggadah, Palestine was under the deepest obligation to Babylonia. For the father of Halakhic study was Hillel, the Babylonian, and among the popular Haggadists there is not a name better known than that of Eleazar the Mede, who flourished in the first century of our era.
