Did Jephthah sacrifice his daughter?

In Judges 11, Jephthah vows to give whatever comes out of the door of his house as a burnt offering. > [**Judges 11:30-40 (ESV)**](http://www.biblegateway.com/passage/?search=Judges%2011:30-&version=ESV) [emphases mine] > > 30 And Jephthah made a vow to the LORD and said, "If you will give the Ammonites into my hand, 31 then **whatever comes out from the doors of my house** to meet me when I return in peace from the Ammonites shall be the LORD’s, and **I will offer it up for a burnt offering**." > 34 Then Jephthah came to his home at Mizpah. And behold, **his daughter came out** to meet him with tambourines and with dances. >39 And at the end of two months, **she returned to her father, who did with her according to his vow that he had made.** 1. Did Jephthah really sacrifice his daughter? This clearly couldn't be the will of God (e.g. <a href="/redirect?url=http%3A%2F%2Fwww.biblegateway.com%2Fpassage%2F%3Fsearch%3DJeremiah%25207%3A31%26version%3DESV" class="external-link" target="_blank" rel="nofollow noopener">Jeremiah 7:31 <i class="fas fa-external-link-alt fa-xs"></i></a>, <a href="/redirect?url=http%3A%2F%2Fwww.biblegateway.com%2Fpassage%2F%3Fsearch%3DJeremiah%252019%3A5%26version%3DESV" class="external-link" target="_blank" rel="nofollow noopener">19:5 <i class="fas fa-external-link-alt fa-xs"></i></a>, <a href="/redirect?url=http%3A%2F%2Fwww.biblegateway.com%2Fpassage%2F%3Fsearch%3DJeremiah%252032%3A35%26version%3DESV" class="external-link" target="_blank" rel="nofollow noopener">32:35 <i class="fas fa-external-link-alt fa-xs"></i></a>). 2. What did Jephthah mean by his vow? 3. Surely he knew who lived in his house, and had some expectations on what could come out of the door?
