Charles Ellicott Commentary Judges 11:7

"And Jephthah said unto the elders of Gilead, Did not ye hate me, and drive me out of my father`s house? and why are ye come unto me now when ye are in distress?" — Judges 11:7 (ASV)

Did not ye hate me? —The elders of Gilead must at least have permitted his expulsion by his brethren.

Therefore. —i.e., with the express desire to repair the old wrong.
