Judges 11:9-11

King James Version

⁹ 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?

¹⁰ And the elders of Gilead said unto Jephthah, The Lord be witness between us, if we do not so according to thy words.

¹¹ Then Jephthah went with the elders of Gilead, and the people made him head and captain over them: and Jephthah uttered all his words before the Lord in Mizpeh.
