Jephthah's Sacrifice In Genesis 22

From the story in Genesis 22 I would say that Jephthah's thought that when he returned home that the first thing that would come out of his door to greet him would be his animal and this would be his sacrifice to the Lord in return for the Lord delivering the Ammonites into his hands but instead of it being an animal it was his precious daughter that was the first to walk out the door and because of his vow that he made to the Lord it resulted in the sacrifice of his daughter. ( Tullock & McEntire, 2006 p.110).
