Judges 11:7 - Joseph Benson’s Commentary on the Old and New Testaments

Did ye not hate me, and expel me And deprive me of all share in my father's goods, which, though a bastard, was due to me? This expulsion of him was the act of his brethren; but he here ascribes it to the elders of Gilead; either because some of his brethren were among these elders, as is very probable from the dignity of this family; or because this act, though desired by his brethren, was executed by the decree of the elders, to whom the determination of all controversies about inheritances belonged; and therefore it was their faults they did not protect him from the injuries of his brethren.
