Jephthah's vow is illustrated in Judges 11, where he promises God a burnt offering if He grants him victory over the Ammonites.
In Judges 11, Jephthah makes a vow to the Lord, promising to offer as a burnt offering whatever comes out of his house to greet him upon his victorious return. This vow is a significant aspect of the narrative as it highlights Jephthah's faith and desperation for deliverance from the Ammonites. Scholars have debated the implications of this vow, particularly whether it was rash or not, but it is referenced in Hebrews 11 as an act of faith. This indicates that God recognized and noted Jephthah's vow despite its horrifying implications.
