The answer is: Jephthah

Judges 11:30-31, 39 - Jephthah made a vow that upon his victorious return he would give to the Lord, as a burnt offering, whatever came out of his house to meet him first. Unfortunately it was his daughter and he was bound by his vow. There is some disagreement among the scholars as to whether he actually sacrificed his daughter or whether she was given to temple service and perhaps something you would like to do some further study on.

The story of Jephthah is indeed one of the most perplexing narratives in the Book of Judges. When Jephthah vowed to sacrifice the first thing that came out of his house, it reveals much about his character and the cultural norms of his time. Some suggest that a strong sense of duty and divine obligation clouded his judgment. Essentially, he placed the value of his vow, and perhaps reputation in the community, above the life of his daughter. It also prompts serious reflections on the nature of oaths in ancient Israel, and how they were seen as binding.

Interestingly, if we look closer, Jephthah's vow echoes among other stories in the Bible where individuals make significant, often rash commitments. In some ways, it's reminiscent of Solomon's rash promises and how they, too, could lead to unintended consequences.

Building upon themes of sacrifice, another critical aspect of this passage is how it wrestles with the concept of divinely sanctioned deeds. Jephthah was a warrior judged for both his capabilities and circumstances, but his narrative serves as a cautionary tale. Readers are left pondering moral dilemmas: What does foremost obedience to one's vow mean when it conflicts with compassion?

Moreover, it's fascinating to note that Jephthah's daughter exemplifies remarkable bravery and resilience. The text implies she embraced a life of unwavering devotion after her father's tragic declaration, providing a nuanced interpretation to her story - one that speaks to personal agency in moments of dire context. These deep intersections of duty and morality resonate through various ethical discussions today.
