Judges 11:8-10

King James Version

⁸ And the elders of Gilead said unto 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.

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.
