How, in later times, the great writings of the Hebrews came to acquire the same exaggerated sacredness, we can also observe. We read in one of the historical books of the Jews that "Nehemiah founded a library and gathered together the writings concerning the Kings, and of the prophets, and the (songs) of David and epistles of Kings concerning temple gifts."[11] This formation of a National Library was really the germ out of which grew the Old Testament. It was a purely civic act by a layman, but it expressed the honor in which the national writings were coming to be held. It is coincident with this that we find a priestly movement to draw a sacred line around the more important writings of the nation.
Tradition has credited Ezra, the priestly coadjutor of Nehemiah, with the first formation of the Old Testament Canon. The two traditions express one and the same fact from the secular and ecclesiastical points of view. In the exile, the stricken nation came to value and honor its national heritage as never before. Its literary sense was quickened by close contact with the civilization of Babylonia, whose great library constituted one of the chief treasures of the central city. It was natural that on their return to their native land the Jews should gather their race-writings and found a National Library.
The genius of Israel had always been religious. Its very literature was pre-eminently religious. That their venerable writings should be received as sacred was thus wholly natural. They were in reality sacred writings.
Moreover, a large part of these writings, and that part largely drawn from very ancient times, was composed of judicial decisions, legislative codes, etc., around which veneration properly gathered. This veneration was heightened by the popular traditions which assigned to Moses the bulk of their legislation, and traced it through him to Jehovah himself. During the exile a remarkable priestly development, which had been running on through two centuries, at least, culminated in a completely organized hierarchy and an elaborate cultus.
In the process of this final development in Babylonia the legislation and histories of the nation were worked over by priestly hands in the priestly spirit. The law of Moses was now for the first time completely set before the people, and on the restoration to Judea was made the law of the land. It became, therefore, in a new sense sacred.
