Judges 11:9

Jephthah 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 .

Jephthah answered, “Suppose you take me back to fight the Ammonites and the Lord gives them to me—will I really be your head?”

And Jephthah said unto 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?
