Judges 11:33

And he smote them from Aroer, the northern city of this name, even till thou come to Minnith, a city not far from Heshbon, even twenty cities, and unto the plain of the vineyards, Abel Keramim, whose location is not known, with a very great slaughter. Thus the children of Ammon were subdued before the children of Israel. Jephthah's victory was a deed of faith.
