Judges 11:7-11

7And Jephthah said to the elders of Gilead, Did not ye hate me, and expel me out of my father's house? and why are ye come to me now when ye are in trouble?

8And the elders of Gilead said to Jephthah, Therefore we have returned to thee now, that thou mayest go with us, and fight against the children of Ammon, and be head over all of us the inhabitants of Gilead.

9And Jephthah said to the elders of Gilead, If ye take me back to fight against the children of Ammon, and Jehovah give them up before me, shall I be your head?

10And the elders of Gilead said unto Jephthah, Jehovah be witness between us, if we do not so according to thy words!

11Then Jephthah went with the elders of Gilead, and the people made him head and captain over them; and Jephthah uttered all his words before Jehovah in Mizpah.
