Judges 11:9

6 And they said to Jephthah, Come and be our chief so that we may make war against the children of Ammon.

7 But Jephthah said to the responsible men of Gilead, Did you not, in your hate for me, send me away from my father's house? Why do you come to me now when you are in trouble?

8 And the responsible men of Gilead said to Jephthah, That is the reason we have come back to you; so go with us and make war against the children of Ammon, and we will make you our head over all the people of Gilead.

9 Then Jephthah said to the responsible men of Gilead, If you take me back to make war against the children of Ammon, and if with the help of the Lord I overcome them, will you make me your head?

10 And the responsible men of Gilead said to Jephthah, May the Lord be our witness: we will certainly do as you say.

11 So Jephthah went with the responsible men of Gilead, and the people made him head and chief over them; and Jephthah said all these things before the Lord in Mizpah.

12 Then Jephthah sent men to the king of the children of Ammon, saying, What have you against me that you have come to make war against my land?
