Judges 11:29-31

Then 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. And Jephthah made a vow to the LORD: “If you give the Ammonites into my hands, whatever 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.”
