Judges 11:30, 31, 35

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

whatever 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.”

When he saw her, he tore his clothes and cried, “Oh no, my daughter! You have brought me down and I am devastated. I have made a vow to the LORD that I cannot break.”
