After Samson came Eli[?], who was both high priest and judge. He directed the civil and religious affairs of the people for forty years, at the close of which the Philistines again invaded the land and oppressed it for twenty years. Samuel was raised up to deliver the people from this oppression, and he judged Israel for some twelve years, when the direction of affairs fell into the hands of Saul, who was anointed king. If Eli and Samuel are included, there were then fifteen judges. But the chronology of this whole period is uncertain.
The historic section of the book is followed by an appendix (17-21), which has no formal connection with that which goes before. It records (a) the conquest (17, 18) of Laish[?] by a portion of the Tribe of Dan[?]; and (b) the almost total extinction of the Tribe of Benjamin[?] by the other tribes, in consequence of their assisting the men of Gibeah [?](19-21). This section properly belongs to the period only a few years after the death of Joshua.
The author of this book is traditionally believed to be Samuel. It was probably composed during Saul's reign, or at the very beginning of David's. The words in 18:30,31, imply that it was written after the taking of the ark of the covenant by the Philistines, and after it was set up at Nob[?] (1 Samuel 21). In David's reign the ark was at Gibeon (1 Chronicles 16:39).
