Judges 11:29-33

29Then the Spirit of Yhwh came upon Jephthah, and he passed over Gilead, and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh of Gilead he passed over unto the children of Ammon. 30And Jephthah vowed a vow unto Yhwh, and said, If thou shalt without fail deliver the children of Ammon into mine hands, 31Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be Yhwh's, and I will offer it up for a burnt offering.12

32So Jephthah passed over unto the children of Ammon to fight against them; and Yhwh delivered them into his hands. 33And he smote them from Aroer, even till thou come to Minnith, even twenty cities, and unto the plain of the vineyards, with a very great slaughter. Thus the children of Ammon were subdued before the children of Israel.3
