Judges 12:7

“And Jephthah judged Israel six years, etc.] After the affair of the Ephraimites, he was acknowledged by all Israel as their judge and supreme governor, but did not live long; being perhaps depressed and worn away with grief, on account of his daughter, and other troubles that attended him: then died Jephthah the Gileadite, and was buried in one of the cities of Gilead: it is not said in what city he was buried, but very probably it was in his own city Mizpeh, where he dwelt. Josephus f253 says it was in his own country, Sebee, a city of Gilead.”

“Jephthah died--After a government of six years, this mighty man of valor died; and however difficult it may be for us to understand some passages in his history, he has been ranked by apostolic authority among the worthies of the ancient church. He was followed by a succession of minor judges, of whom the only memorials preserved relate to the number of their families and their state [Jdg 12:8-15]. Next: Judges Chapter 13”

“Jephthah judged Israel six years, though most probably only the tribes on the east of the Jordan. When he died, he was buried in one of the towns of Gilead. The plural גלעד בּערי is used quite indefinitely, as in Gen 13:12; Neh 6:2, etc. (see Ges. Lehrgeb. p. 665), simply because the historian did not know the exact town. Judges 12:8”
