Judges 11:11, 29

Then Jephthah went with the elders of Gilead, and the people made him head and commander over them; and Jephthah spoke all his words before the LORD in Mizpah.

Then the Spirit of the LORD came upon Jephthah, and he passed through Gilead and Manasseh, and passed through Mizpah of Gilead; and from Mizpah of Gilead he advanced toward the people of Ammon.
