Hebrew literature contains some of the most profound and most influential productions of the human spirit. It constitutes a potent factor in modern civilization, and possesses merits which place it far above most other literatures of the world. The common salutation of the Hebrew is "Peace," while that of the Greeks is "Grace," and that of the Romans, "Safety." The Greek sought after grace, or intellectual and bodily perfection, and the power of artistic accomplishment. The Roman's ideal was strength and security of life and property.
