It is possible, however, to fix the date more precisely. The most remarkable element in the legislation is its repeated and emphatic demand for the centralization of worship in "the place which Jehovah your God shall choose out of all your tribes to put His name there," xii. 5. Only by such a centralization could the Jehovah worship be controlled which, at the numerous shrines scattered over the country, was being stained and confused by the idolatrous practices which Israel had learned from the Canaanites. This demand is recognized as something new, xii. 8. In the ninth and eighth centuries, when the prophetic narratives of Genesis were written,[1] these shrines, which were the scenes of an enthusiastic worship, are lovingly traced back to an origin in patriarchal times. As late as 750-735 B.C., Amos and Hosea, though they deplore the excesses which characterized those sanctuaries, and regard their worship as largely immoral, do not regard the sanctuaries themselves as actually illegal; consequently Deuteronomy must be later than 735. But the situation was even then so serious that it must soon have occurred to men of practical piety to devise plans of reform, and that the only real remedy lay in striking the evil at its roots, i.e. in abolishing the local shrines. The first important blow appears to have been struck by Hezekiah, who, possibly under the influence of Isaiah, is said to have removed the high places (2 Kings xviii. 4), and the movement must have been greatly helped by the immunity which the temple of Jerusalem enjoyed during the invasion of Judah by Sennacherib in 701 B.C. But the singular thing is that no appeal was made in this reformation to a book, as was made in 621, and as it is natural to suppose would have been made, had such a book been in existence. Somewhere then between Hezekiah and Josiah we may suppose the book to have been composed. [Footnote 1: See below]
