Judges 11:11, 29

So Jephthah went with the elders of Gilead, and the people made him their ruler and commander of the army. At Mizpah, in the presence of the LORD, Jephthah repeated what he had said to the elders.

At that time the Spirit of the LORD came upon Jephthah, and he went throughout the land of Gilead and Manasseh, including Mizpah in Gilead, and from there he led an army against the Ammonites.
