Judges 11:5-9

5And when the Ammonites made war against Israel, the elders of Gilead went to bring Jephthah from the land of Tob.

6And they said to Jephthah, "Come and be our leader, that we may fight against the Ammonites."

7But Jephthah said to the elders of Gilead, "Did you not hate me and drive me out of my father's house? Why have you come to me now when you are in distress?"

8And the elders of Gilead said to Jephthah, "That is why we have turned to you now, that you may go with us and fight against the Ammonites and be our head over all the inhabitants of Gilead."

9Jephthah said to the elders of Gilead, "If you bring me home again to fight against the Ammonites, and the Lord gives them over to me, I will be your head."
