What vow did Jephthah make in Judges?

Jephthah's vow in the Book of Judges is significant as it reflects the intense and often tragic nature of his character and the narrative. He vowed to offer as a burnt offering the first living thing that came out of his house to greet him if he was victorious in battle against the Ammonites. This vow illustrates themes of sacrifice, the consequences of impulsive promises, and the interaction between divine providence and human action.

When he returned home after winning the battle, it was his daughter who first came out to greet him, leading to the devastating fulfillment of his vow. This story serves as a powerful cautionary tale about the implications of one's commitments and the seriousness with which vows should be made. In the context of the other options, they either misrepresent Jephthah’s specific vow or focus on aspects unrelated to the central narrative.
