The people, the leaders of Gilead, said to one another, “Who is the man who will begin to fight against the sons of Ammon? He shall become head over all the inhabitants of Gilead.”

So Jephthah said to the elders of Gilead, “If you take me back to fight against the sons of Ammon and the Lord gives them up to me, will I become your head?”

However, the hair of his head began to grow again after it was shaved off.
