Judges 11:30 - 11:31
30 Then Jephthah made a vow to Yahweh and said, “If You will indeed give the sons of Ammon into my hand, 31 then it shall be that whatever comes out of the doors of my house to meet me when I return in peace from the sons of Ammon, it shall be Yahweh’s, and I will offer it up as a burnt offering.”
