Judges 11:11, 29

So Jephthah went with the elders of Gilead, and the people made him head and leader over them. And Jephthah repeated everything that he had promised before the LORD at Mizpah.

Then the Spirit of the LORD came upon Jephthah, and he passed through Gilead and Manasseh, and Mizpah of Gilead, and from Mizpah of Gilead he passed on to the Ammonites.
