The best method of studying any history is in its great epochs and periods. The eras of Hebrew history group themselves clearly, in orderly progression.
Hebrew history properly begins with this era. The tribes of Israel when first resolved by the glass of history, appear upon the Arabian border of Egypt, as occupants of the rich pasture lands of Goshen. They were a branch of a large Semitic family, which included Moab, Edom, Ammon and other familiar tribes. Of the social, intellectual and religious status of the Hebrews at this period we have little definite information. They would seem to have been on the usual plane of races which have entered the semi-nomadic stage, and which are gradually substituting agricultural pursuits for a roving shepherd life. Oppressed by Egypt they revolt, and begin a migration backward toward the north and east.
The soul of this movement was Moses; a real historic figure, worthy, as we can see through the mists around him, of the imposing form which Michael Angelo has given him. A great man is nearly always to be found at the core of a great social growth, charging the latent tendencies of a race with energy, and shaping their action upon the form of his mind. "An institution is the lengthened shadow of a man," writes Emerson. Judaism is the lengthened shadow of Moses. Whatever else Moses may have done, he proved himself the architect of Israel, by laying the foundation that determined the form and size of the later structure. He taught his simple people to recognize Jehovah as their tribal God. What this name meant in the conception of the people before his time is by no means clear to us now. It appears to have stood for the personification of some one of the forms of nature's forces, that arrest upon themselves the nomad's vague sense of the Infinite and Divine in the world about him. Around the Power felt in Saturn or the Sun, Moses threw the spell of an awe which is deeper far than that awakened by the starry heavens above man--the awe aroused by the moral law within man. He gave his rude children a noble moral code, the original form of the Decalogue. These Ten Words were issued as the law of Jehovah. Jehovah then was the source and authority of the laws which the conscience owned. The moral law was his body of statutes. To keep this law was the way to please Him. His commands reached through rites and ordinances to conduct and character. His demands were not for sacrifices, but for good lives. His worship was aspiration and endeavor after goodness.
