Jephthah came to Mizpah to his house; and, behold, his daughter came out to meet him with tambourines and with dances: and she was his only child; besides her he had neither son nor daughter.
(8) We have already noted that Jephthah's name is listed in the roster of the heroes of faith in  Hebrews 11, along with David and Samuel, and due to the fact of human sacrifice having been forever and always an abomination to the Lord, it is impossible to believe that Jephthah would have been so favorably mentioned in the N.T. if indeed he had offered up a human sacrifice in the person of his daughter.  Such a thing simply cannot fit what is written.
