Female chastity was jealously guarded. When a young prince seduced Dinah, the daughter of Jacob, although offering honorable marriage, with any amount of dowry, the vengeance of the brothers could only be appeased by blood; and the history of Joseph shows that purity was regarded as a virtue in man as well as in woman. Such, then, was the patriarchal stock,--the seed-form of the great and chosen nation. Let us now glance at the influences which nourished it through the grand growth of the prophetic or national period, up to the time of its consummate blossom and fruit in the Christian era. Moses was the great lawgiver to mold this people into a nation. His institutes formed a race of men whose vital force has outlived conquest, persecution, dispersion, and every possible cause which could operate to destroy a nationality; so that, even to our time, talent and genius spring forth from the unwasted vigor of these sons and daughters of Abraham. The remarkable vigor and vitality of the Jewish race, their power of adaptation to every climate, and of bearing up under the most oppressive and disadvantageous circumstances, have attracted the attention of the French government, and two successive commissions of inquiry, with intervals of three or four years between, have been instituted, "on the causes of the health and longevity of the Jewish race." In the "Israelite" of February 9, 1866, we have, on this subject, the report of M. Legoyt, chief of a division of the ministry of commerce and public works, one of the first statisticians of France. He says: "We have seen that all the documents put together are affirmative of an exceptional vitality of the Jews. How can this phenomenon be explained? Dietrici, after having demonstrated its existence in Prussia, thinks it is to be attributed to greater temperance, a better regulated life, and purer morals. This is likewise the opinion of Drs. Neufville, Glatter, and Meyer. Cases of drunkenness, says Dietrici, frequent among the Christians, occur very rarely among the Jews. This regularity and discipline, and greater self-control, of Jewish life is confirmed by the criminal statistics of Prussia, which show fewer Jews condemned for crime." M. Legoyt goes on to account for this longevity and exceptional vitality of the Jews by the facts of their family life: that early marriages are more common; that great care is taken to provide for the exigencies of marriage; that there are fewer children born, and thus they are better cared for; that family feeling is more strongly developed than in other races; that the Jewish mother is the nurse of her own infant, and that great care and tenderness are bestowed on young children.
