29Then the Spirit of the LORD came on Jephthah. He crossed Gilead and Manasseh, passed through Mizpah of Gilead, and from there he advanced against the Ammonites. 30And Jephthah made a vow to the LORD : “If you give the Ammonites into my hands,
31whatever comes out of the door of my house to meet me when I return in triumph from the Ammonites will be the LORD ’s, and I will sacrifice it as a burnt offering.”
