Judges 11:29-31

29Then the Spirit of the Lord came upon Jephthah, and he passed through Gilead and Manasseh, and passed through Mizpah of Gilead; and from Mizpah of Gilead he advanced toward the people of Ammon.

30And Jephthah made a vow to the Lord, and said, “If You will indeed deliver the people of Ammon into my hands,

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