Judges 11:29-33

29Then 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.

30Jephthah made a vow to the Lord and said, “If You will indeed give the Ammonites into my hand,

31then whatever comes out of the doors of my house to meet me when I return in peace from the Ammonites, it shall be the Lord’s, and I will offer it up as a burnt offering.”

32Then Jephthah crossed over to the Ammonites to fight with them; and the Lord gave them into his hand.

33And from Aroer to the entrance of Minnith he struck them, twenty cities, and as far as Abel-keramim (brook by the vineyard), with a very great defeat. So the Ammonites were subdued and humbled before the Israelites.
