Judges 11:5-9

5And it was so, that, when the children of Ammon made war against Israel, the elders of Gilead went to fetch Jephthah out of the land of Tob; 6and they said unto Jephthah, Come and be our chief, that we may fight with the children of Ammon. 7And 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? 8And the elders of Gilead said unto Jephthah, Therefore are we turned again to thee now, that thou mayest go with us, and fight with the children of Ammon; and thou shalt be our head over all the inhabitants of Gilead. 9And Jephthah said unto the elders of Gilead, If ye bring me home again to fight with the children of Ammon, and Jehovah deliver them before me, shall I be your head?
