Judges 11:29-31

29The Spirit of the Lord came on Jephthah, who traveled through Gilead and Manasseh, and then through Mizpah of Gilead. He crossed over to the Ammonites from Mizpah of Gilead.

30Jephthah made this vow to the Lord: “If you in fact hand over the Ammonites to me,

31whoever comes out the doors of my house to greet me when I return safely from the Ammonites will belong to the Lord, and I will offer that person as a burnt offering.”
