Talmud supplied the deficiency and completed a perfect whole. While yet in the Wilderness, Moses commanded the Israelites to establish courts and appoint judges for the administration of justice as soon as they were settled in Palestine.[58] This clearly indicates that the great lawgiver did not intend his ordinances and injunctions to be final and exclusive. Having furnished a foundation for the scheme, he anticipated that the piety, judgment, and learning of subsequent ages would do the rest. His expectations were fulfilled in the development of the traditions afterwards embodied in the Mishna, which is the principal component part of the Talmud. As before suggested, with the growth in population and the ever-increasing complications in social, political, and religious life, and with the general advance in Hebrew civilization, Mosaic injunction began to prove entirely inadequate to the national wants. In the time intervening between the destruction of the first and second Temples, a number of Mosaic laws had become utter anachronisms; others were perfectly impracticable, and several were no longer even understood. The exigencies of an altered mode of life and the changed conditions and circumstances of the people rendered imperative the enactment of new laws unknown to the Pentateuch. But the divine origin of the Hebrew system of law was never for a moment forgotten, whatever the change and wherever made. The Rabbins never formally repealed or abolished any Mosaic enactment. They simply declared that it had fallen into desuetude. And, in devising new laws rendered necessary by changed conditions of life they invariably invoked some principle or interpretation of the Written Law. In the declining years of Jewish nationality, many characteristic laws of the Pentateuch had become obsolete. The ordinance which determined the punishment of a stubborn and rebellious son; the enactment which commanded the destruction of a city given to idolatry; and, above all, the _lex talionis_ had become purely matters of legend. On the other hand, many new laws appear in the Talmud of which no trace whatever can be discovered in the Pentateuch. "The Pharisees," says Josephus, "have imposed upon the people many laws taken from the tradition of the Fathers, which are not written in the law of Moses."[59] The most significant of these is the one providing for Antecedent Warning in criminal prosecutions, the meaning and purpose of which will be fully discussed in another chapter.
