The first major section in the book (1:1-3:6) explains very clearly why the period of the judges was a dark chapter in Israel's history. God revealed the reasons for Israel's apostasy and consequent national problems in terms too clear to miss.
The years immediately following Joshua's death saw a transition from success to failure. The events of this period set the scene for the amphictyony (rule by judges) and provide a background for the main part of the book (3:7-16:31).
"The Book of Judges may be viewed as having a two-part introduction (1:1-2:5 and 2:6-3:6) and a two-part epilogue (17:1-18:31 and 19:1-21:25). Parallel ideas and motifs link the first introduction (1:1-2:5) with the second epilogue (19:1-21:25), and in like manner the second introduction (2:6-3:6) with the first epilogue (17:1-18:31)."19
"The judges are twelve in number, reckoning either Deborah or Barek as a judge and omitting Abimelech, whose status in fact depended wholly on his descent from Gideon, and who was in effect not a deliverer', and a judge' only in the sense of a local ruler on his own account."60
Notice that the writer recorded seven examples of oppression and deliverance (by Othniel, Ehud, Shamgar, Deborah, Gideon, Jephthah, and Samson). This sevenfold scheme gives the impression of totality to Israel's degeneration. It also suggests that the writer viewed these disasters as fulfillments of the curses in Leviticus 26 where the number seven occurs four times (Lev. 26:18, 21, 24, and 28; cf. Deut. 28:25).61
The total number of judges cited is 12. By selecting 12 judges the writer may also have been suggesting that all 12 tribes of Israel had apostatized. One writer argued that these 12 judges each did their work in a different month, thus adding another impression of completeness to the record.62
Certain formulaic expressions appear in 2:11-23 and then recur in the record of Israel's apostasy (3:7-16:31). However, as noted in the table below, they appear with less frequency as the narrative proceeds. Having established the pattern, the writer did not feel compelled to repeat these expressions as frequently since the reader learns to anticipate them as the narrative unfolds. The breakdown of these expressions is a rhetorical device that parallels and reflects the general moral and spiritual disintegration in Israel as a whole.63
The following two extended incidents (ch. 17-21) differ from the records of the judges just completed (chs. 3-16). They are not accounts of the activities of any of Israel's judges. They are the record of events that took place during the period of the judges that throw light on conditions in Israel during this era. The purpose behind their inclusion seems to have been to illustrate even more clearly ". . . the low moral standards, . . . the debased religious conceptions and . . . the disordered social structure"in Israel.305
"As was the case in the earlier chapters of the Book of Judges [1:1-3:6], these chapters deal with the subject of spiritual apostasy and its effects upon the nation of Israel."306
Whereas chapters 3-16 record Israel's struggles with her external enemies, chapters 17-21 document the internal conditions of the nation that made her so weak. In chapters 17-18 we see Israel abandoning God, and in chapters 19-21 we see her destroying herself.
The town of Bethlehem features in each of three stories. These stories are Micah and the Danites (chs. 17-18), the Levite and the Benjamites (chs. 19-21), and the story of Ruth in the Book of Ruth. Therefore some scholars refer to this section of Scripture as the "Bethlehem trilogy."These stories also share other themes and motifs.
"They concern individuals in more or less private settings whose identities and activities are nevertheless inseparable from and crucial to a full understanding of the Davidic monarchy which followed them. Accounts of actual events that transpired in the days of the judges, they are included in the sacred record for the purpose of tracing the roots of the Davidic dynasty and justifying its existence in opposition to Saul."307
The first incident (chs. 17-18) describes the fate of the Danites, and the second (chs. 19-21) the fate of the Benjamites. Both tribes received land in Israel's heartland, between Judah and Ephraim, the tribes that would, after the monarchy divided, lead the Southern and Northern Kingdoms respectively. By selecting incidents from these tribes, the narrator showed that the degenerating tendency in Israel was not just a problem in the fringe territories. Canaanite influence had infected the heart of the nation.
Both Dan and Benjamin found themselves in dire straits but for different reasons. The Danites could not settle into their allotted inheritance because of Canaanite influence, and the Benjamites could not remain in theirs because of their hostile Israelite brethren. In both instances a nameless Levite with Bethlehem-Judah (17:7-8; 19:1-2) and Mt. Ephraim (17:1; 19:1) connections precipitated the crisis. Both accounts include priestly characters inquiring of God concerning the outcome of a proposed course of action (18:5-6; 20:27-28), and both conclude with a reference to Shiloh (18:31; 21:19-24). In both accounts military contingents of 800 men play a crucial role (18:11, 16, 25; 20:47; 21:7, 12, 14, 16-17, 23), and both contain references to the absence of a king in Israel (17:6; 18:1; 19:1; 21:25). These parallel phenomena have the effect of making the reader conclude that the Canaanization of Israel had become complete.308
