All Hebrew manuscripts, as is well known, are of comparatively recent date, owing to the strict rule of the Jewish Schools that any manuscript which had in the slightest degree suffered from time or use was to be instantly destroyed. The oldest Hebrew manuscript is supposed to be the Codex Babylonicus at St. Petersburg (A.D. 916), unless one recently discovered by Dr. Ginsburg in the British Museum be older. Most Hebrew manuscripts are later than the twelfth century. The variations in the Samaritan Pentateuch, and in the Septuagint version--the latter of which are often specially valuable as indications of the original text--furnish abundant proof that no miracle has been wrought to preserve the text of Scripture from the changes and corruptions which always arise in the course of constant transcriptions. A further and serious difficulty in the reproduction of events in their historic exactitude is introduced by the certainty that many books of the Bible, in their present form, represent the results arrived at after their recension by successive editors, some of whom lived many centuries after the events recorded. In the Books of Kings we probably see many _nuances_ which were not introduced till after the epoch-making discovery of the Book of the Law (perhaps the essential parts of the Book of Deuteronomy) in the reign of Josiah, B.C. 621 (2 Kings xxii. 8-14). It is, for instance, impossible to declare with certainty what parts of the Temple service were really coæval with David and Solomon, and what parts had arisen in later days. There appear to be liturgical touches, or alterations as indicated by the variations of the text in 1 Kings viii. 4, 12, 13. In xviii. 29-36 the allusion to the _Minchah_ is absent from the LXX. in verse 36, and in 2 Kings iii. 20 another reading is suggested. B. As regards the difficult question of _Chronology_ we need add but little to what has been elsewhere said.[31] Even the most conservative critics admit that (1) the numbers of the Biblical text have often become corrupt or uncertain; and (2) that the ancient Hebrews were careless on the subject of exact chronology. The Chronology of the Kings, as it now stands, is historically true in its general outlines, but in its details presents us with data which are mutually irreconcilable. It is obviously artificial, and is dominated by slight modifications of the round number 40.[32] Thus from the Exodus to the Building of the Temple is stated at 480 years, and from that period to the fiftieth year of the Exile also at 480 years. In the Chronicles there are eleven high priests from Azariah ben-Ahimaaz to the Exile of Jozadak, which, with the Exile period, gives twelve generations of 40 years each. Again, from Rehoboam to the Fall of Samaria in the sixth year of Hezekiah, following the 40 years' reign of Saul, of David, and of Solomon, we have:--
