Judges 11:29-31

29Then the Ruach Adonai came upon Jephthah, so he marched through Gilead and Manasseh, and passed through Mizpah of Gilead, and from Mizpah of Gilead he crossed over to the children of Ammon.

30Then Jephthah vowed a vow to Adonai and said, “If You will indeed give the children of Ammon into my hand,

31then it will be that whatever comes out of the doors of my house to meet me when I return safely from the children of Ammon, it will be Adonai’s, and I will offer it up as a burnt offering.”
