Judges 11:30-32

30And Jephthah made a vow to the LORD : “If you give the Ammonites into my hands,

31whatever 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.” 32Then Jephthah went over to fight the Ammonites, and the LORD gave them into his hands.
