Judges 11:30-31, 35

Jephthah made a vow to the LORD and said, “If You will indeed give the Ammonites into my hand, then whatever comes out of the doors of my house to meet me when I return in peace from the Ammonites, it shall be the LORD’S, and I will offer it up as a burnt offering.”

And when he saw her, he tore his clothes [in grief] and said, “Alas, my daughter! You have brought me great disaster, and you are the cause of ruin to me; for I have made a vow to the LORD, and I cannot take it back.”
