Judges 11:8

5 It was so, that when the children of Ammon made war against Israel, the elders of Gilead went to get Jephthah out of the land of Tob;

6 and they said to Jephthah, Come and be our chief, that we may fight with the children of Ammon.

7 Jephthah said to the elders of Gilead, Didn`t you hate me, and drive me out of my father`s house? and why are you come to me now when you are in distress?

8 The elders of Gilead said to Jephthah, Therefore are we turned again to you now, that you may go with us, and fight with the children of Ammon; and you shall be our head over all the inhabitants of Gilead.

9 Jephthah said to the elders of Gilead, If you bring me home again to fight with the children of Ammon, and Yahweh deliver them before me, shall I be your head?

10 The elders of Gilead said to Jephthah, Yahweh shall be witness between us; surely according to your word so will we do.

11 Then Jephthah went with the elders of Gilead, and the people made him head and chief over them: and Jephthah spoke all his words before Yahweh in Mizpah.
