Thus one of the chief elements in the providential training of the Hebrews as the heralds and exponents of the most exalted religious and ethical truths revealed before the advent of the Prophet of Nazareth was the fact that they were the heirs and interpreters of the best that had been hitherto attained. Babylonia, Egypt, and later, Persia and Greece, each contributed their noblest beliefs and ideals. In the Israelites the diverse streams of divine revelation converged. The result is that, instead of many little rivulets, befouled by errors and superstitions, through their history there flowed a mighty stream, ever becoming broader and deeper and clearer as it received fresh contributions from the new fountains of purest revelation that opened in Hebrew soil. [Sidenote: _In close geographical relations to the earlier civilizations_] Clear evidences of the divine purpose to be realized through the obscure peasant people who lived among the uplands of central Canaan are found in a study of the characteristics of the Old Testament world. It is indeed the earliest and one of the most significant chapters in divine revelation. Most of its area is a barren wilderness, supporting only a small nomadic population. The three fertile spots are Babylonia, Canaan, and Egypt. The first and last are fitted by nature and situation to be the seats of powerful civilizations, destined to reach out in every direction. Canaan, on the contrary, is shut in, with no good harbors along the Mediterranean; and its largest river system leads to the Dead Sea, far below the surface of the ocean,--an effective negation to all commerce. Although thus shut in by itself, Canaan lies on the isthmus of fertile land that connects the great empires of the Nile and the Euphrates. On the east and south it is always subject to the influences and waves of immigration, that come from the Arabian desert. It attracted from their nomadic life the ancestors of the Israelites, and during their early period of development gave them a secluded home. When they were ready to learn the larger lessons in the stream of life, Egypt and the great empires of the Tigris and Euphrates valley contended for them, conquered and ultimately scattered them throughout the then known world. While their conquerors, Egypt, Assyria, Babylonia, Persia, Greece, and Rome, the greatest powers of the ancient world, took from them their gold and their freedom, from the same conquerors they appear to have received the infinitely more precious treasures of tradition and thought.
