By the side of the ceremonial element in the Law there ripened gradually an expansion of its moral precepts. The sacred books were expounded by the Scribes. The preacher in the synagogue came to touch the people's heart often more closely and delicately than the priest with his bloody sacrifices and his imposing liturgies. Spontaneity, inspiration, prophetic power, was no longer present, but in the guise of comment and interpretation there grew up a gentler, humaner morality. The moral value of labor and industry came into recognition. There were teachers like Hillel and Gamaliel in whom devout piety and homely practice went hand in hand. In the ethics of Judaism--under all these various forms of "the Law and the Prophets"--the distinctive note, compared with the ethics of Greece and Rome, was chastity. The ideal Greece represented wisdom and beauty; the ideal Rome was valor and self-control; the ideal Israel was the subjugation of sense to spirit, the approach of man to God by purity of life. The twofold service of Judaism was to impress this special note of chastity on human virtue, and to give to virtue the wings of a great hope. The flowering of that hope was in Christianity; the preparation for it comes now before us. Under the rule of Alexander's successors the Jewish system, with its mixture of ethics and ritual, came in collision with the ideas and practice of degenerate Greek culture,--pleasure-loving, nature-worshiping, sensual, with gymnastics and aesthetics, tolerant and tyrannical. The two systems were hostile alike in their virtues and vices. The Greek ruler put down with a strong hand the religious and patriotic scruples of his Jewish subject. The Jew bore persecution with the tough endurance of his race, then rose in revolt with the fierce courage and religious fervor of his race. He won his last victory in the field of arms. Brief was the independence, soon followed by inglorious servitude; but its sufferings and triumphs had fused the nation once more into invincible devotion to the Law of their God, and had rooted in their hearts a principle of hope which in varying forms and growing power was to change the aspect of human life.
