Bible Verses About Jephthah: Leads the host of Israel against the Ammonites

Then the Spirit of the LORD came upon Jephthah, and he passed through Gilead and Manasseh, then through Mizpah of Gilead. And from there he advanced against the Ammonites.

Jephthah made this vow to the LORD: “If indeed You will deliver the Ammonites into my hand,

then whatever comes out the door of my house to greet me on my triumphant return from the Ammonites will belong to the LORD, and I will offer it up as a burnt offering.”

So Jephthah crossed over to the Ammonites to fight against them, and the LORD delivered them into his hand.

With a great blow he devastated twenty cities from Aroer to the vicinity of Minnith, as far as Abel-keramim. So the Ammonites were subdued before the Israelites.
