[Sidenote: Period represented by the primitive codes]
Here the primitive ceremonial decalogue has been expanded into the third and fourth group given above. Like the Judgments, these decalogues bear testimony to their northern origin, and probably they also have had much the same history, although their relation to the primitive decalogue and the fact that they are prefixed and added to the solid group of Judgments, would seem to indicate that they were somewhat later. These two collections, together with their older prototype, the ancient decalogue, represent the growth of Israel's laws during the four centuries beginning with Moses and extending to about 800 B. C. To distinguish them from later collections they may be designated as the Primitive Codes.
[Sidenote: The need for new laws]
The eighth and seventh centuries before Christ which brought to the Hebrews great crises and revolutionary changes in both their political and religious life, witnessed the epoch-making work of Amos, Hosea, Isaiah, and Micah. This remarkable group of prophets proclaimed so many new principles that a fundamental revision and expansion of Israel's primitive codes became necessary in order to adapt the latter to the new needs of the age. The reactionary reign of Manasseh had also brought out plainly the contrast between the older heathen cults, still cherished by the people, and the exalted ideals of the true prophets. If the prophetic teachings were to become operative in the life of the nation, it was also seen that they must be expressed in concrete legal enactments, which could be universally understood and definitely enforced.
[Sidenote: Application of prophetic principles in the life of the people]
Accordingly, a group of prophets, disciples of the older masters, and inspired by the spirit of reform, devoted themselves to this all-important task. The results of their work are represented by the prophetic law-book of Deuteronomy. Through its pages glow the new ethical teachings of the prophets of the Assyrian period. The elements of Hosea's doctrine, love to God and love to men and kindness to the needy and oppressed, in their new setting and application, make it one of the evangels of the Old Testament. Its lofty standards of justice and social responsibility reflect the impassioned addresses of Amos and Hosea. Since the new laws, as a whole, represented the practical application of the messages of the prophets to life, they were justly and appropriately placed in the mouth of Moses, the real and traditional head of the nation and of the prophetic order.
[Sidenote: Relation to the older laws]
A comparison of this prophetic law-book with the older primitive laws shows that the latter were made the basis of the new codes, since most of them, in revised form, are also found in Deuteronomy. The prophetic lawmakers, however, in the same spirit that actuated Jesus in his attitude toward the ancient law, freely modified, supplemented, and in some cases substituted for the primitive enactments, laws that more perfectly embodied the later revelation.
[Sidenote: Promulgation and date of the prophetic codes]
The nature of the reforms instituted by Josiah, according to II Kings xxii., clearly prove that the laws which inspired them were those of Deuteronomy, and that this was the law-book discovered in the temple by Hilkiah the priest and publicly read and promulgated by the king in 621 B.C. Originally it was probably prepared by the prophetic reformers as a basis for their work; but it incorporates not only most of the primitive codes, but also many other ancient laws and groups of laws, some doubtless coming from the earliest periods of Israel's history. It also appears to have been further supplemented after the reformation of Josiah. In general it represents the second great stage in Old Testament law, as it rapidly developed between 800 and 600 B.C. under the inspiring preaching of the remarkable prophets of the Assyrian period.
