After Gideon dies in Judges 8, we're given two short stories at the start of Judges 10:
After Abimelech there arose to save Israel Tola the son of Puah, son of Dodo, a man of Issachar, and he lived at Shamir in the hill country of Ephraim. And he judged Israel twenty-three years. Then he died and was buried at Shamir.
After him arose Jair the Gileadite, who judged Israel twenty-two years. And he had thirty sons who rode on thirty donkeys, and they had thirty cities, called Havvoth-jair to this day, which are in the land of Gilead. And Jair died and was buried in Kamon.
After that the Jephthah cycle begin and occupies the next couple of chapters. What purpose do these vignettes have in the larger narrative of Judges? Are they integrated at all into the narrative? Or do they just exist as part of a completionist project on behalf of the author to catalog all the deliverers of Israel during this time periord?
