The Book of Judges falls into three parts, namely, (1) Judg. i. 1-ii. 5, which intrudes, as has already been observed, between the close of Joshua and its immediate sequel in Judges ii. 6 ff.; (2) Judg. ii. 6-xvi. 31, stories of a succession of champions and deliverers of Israel in the centuries preceding the establishment of the kingdom; (3) Judg. 17-18; 19-21, two additional stories laid in the time of the Judges. In the Christian Bibles the story of Ruth, which also is said to have occurred in the days of the Judges, follows. The introduction, Judg. ii. 6-iii. 6, gives a summary of the whole period: as soon as Joshua and his generation had passed away, the Israelites fell away from the religion of Jehovah, and worshipped the gods of Canaan; indignant at this defection, he allowed them to be overrun and subdued by their enemies; when in their distress they turned to their own God for help, he raised them up champions who delivered them; but their amendment was brief, they presently relapsed into heathenism; and so it went on from bad to worse. In correspondence with this general scheme each epoch in the history is opened in some such way as this: The Israelites again did what was evil in the sight of Jehovah; he delivered them into the power of such and such a tyrant or nation; when they cried unto him, he raised up so and so as a deliverer. Thereupon follows the story of the deliverance (see iii. 7-11; iii. 12-15; iv. 1 ff.). Sometimes, as in vi. 1-10, x. 6-18, these preambles are expanded, but the purport remains the same. Another feature of the book is the systematic chronology in which the frequency of the numbers twenty, forty, and eighty (forty years being in the Old Testament equivalent to a generation) at once strikes the attention; see iii. 11, 30; iv. 3; v. 31; viii. 28; xiii. 1; xv. 20 (xvi. 31). In several other instances the figures vary a little on either side of twenty (eighteen, twenty-two, etc.). The duration of the oppression is given in the introduction of the story; the period of peace and prosperity which succeeded the deliverance, at the end; see, e.g., iv. 3; v. 31. In the same way the life of Moses is divided into three parts of forty years each; Eli judged Israel forty years; David and Solomon each reigned forty years. It can hardly be doubted that this chronology is artificial, and that the key to it is found in 1 Kings vi. 1, which reckons four hundred and eighty years (i.e. twelve generations) from the exodus to the building of Solomon's temple; but the actual figures in Judges and Samuel do not foot up to this sum, and there are some gaps in the series, namely, the years of Joshua after the conquest, the rule of Samuel, and that of Saul. The symmetry of the scheme has been broken by intrusions or accidental omissions in the later history of the book.
