Judges 11:5-9

5And it was so, that when the children of Ammon made war against Israel, the elders of Gilead went to bring Jephthah out of the land of Tob: 6And they said to Jephthah, Come, and be our captain, that we may fight with the children of Ammon. 7And Jephthah said to the elders of Gilead, Did ye not hate me, and drive me out of my father’s house? and why have ye come to me now when ye are in distress? 8And the elders of Gilead said to Jephthah, Therefore we turn again to thee now, that thou mayest go with us, and fight against the children of Ammon, and be our head over all the inhabitants of Gilead. 9And Jephthah said to the elders of Gilead, If ye bring me home again to fight against the children of Ammon, and the LORD deliver them before me, shall I be your head?
