Judges 11:11, 30, 31, 35, 36

So Jephthah went with the elders of Gilead, and the people made him head and commander over them. And he repeated all his words before the LORD in Mizpah.

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.”

“My father,” she replied, “you have given your word to the LORD. Do to me just as you promised, now that the LORD has avenged you of your enemies, the Ammonites.
