According to Judges 11-12, Jephthah the Gileadite lead Israel only after first being cast aside by his brothers, as his mother was a prostitute. Eventually, his brothers came to him for help defeating the Ammonites. He responds with the all-too-human “oh so you want me now that you need me.” Their response is to offer him the role of king. He does ultimately defeat the Ammonites but makes a vow to God that the first thing to walk through his door when he gets home he would offer as a sacrifice. He is harrowed when his only child and daughter greets him with song and dance - the first to exit the home. He remains faithful to God and offers her.

I do not think that he actualWhile no follow up is given, we know that he continued to rule for six years.
