Book of Judges in the Bible Encyclopedia - ISBE

3. Contents: The Book of Jdg consists of 3 main parts or divisions, which are readily distinguished. (1) Introductory, Judges 1 through 2:5. A brief summary and recapitulation of the events of the conquest of Western Israel, for the most part parallel to the narrative of Joshua, but with a few additional details and some divergences from the earlier account, in particular emphasizing (Jdg 1:27-36) the general failure of the Israelites to expel completely the original inhabitants of the land, which is described as a violation of their covenant with Yahweh (Jdg 2:1-3), entailing upon them suffering and permanent weakness. The introductory verse (Jdg 1:1), which refers to the death of Joshua as having already taken place, seems to be intended as a general indication of the historical period of the book as a whole; for some at least of the events narrated in Jdg 1 through 2:5 took place during Joshua's lifetime. (2) The Central and Main Portion, Judges 2:6 through 16. A series of narratives of 12 "judges," each of whom in turn, by his devotion and prowess, was enabled to deliver Israel from thralldom and oppression, and for a longer or shorter term ruled over the people whom he had thus saved from their enemies. Each successive repentance on the part of the people, however, and their deliverance are followed, on the death of the judge, by renewed apostasy, which entails upon them renewed misery and servitude, from which they are again rescued when in response to their prayer the Lord "raises up" for them another judge and deliverer. Thus the entire history is set as it were in a recurrent framework of moral and religious teaching and warning; and the lesson is enforced that it is the sin of the people, their abandonment of Yahweh and persistent idolatry, which entails upon them calamity, from which the Divine long-suffering and forbearance alone makes for them a way of escape...
