31. whatsoever cometh forth of the doors of my house to meet me—This evidently points not to an animal, for that might have been a dog; which, being unclean, was unfit to be offered; but to a person, and it looks extremely as if he, from the first, contemplated a human sacrifice. Bred up as he had been, beyond the Jordan, where the Israelitish tribes, far from the tabernacle, were looser in their religious sentiments, and living latterly on the borders of a heathen country where such sacrifices were common, it is not improbable that he may have been so ignorant as to imagine that a similar immolation would be acceptable to God. His mind, engrossed with the prospect of a contest, on the issue of which the fate of his country depended, might, through the influence of superstition, consider the dedication of the object dearest to him the most likely to ensure success.

     Jud 11:32, 33. HE OVERCOMES THE AMMONITES.

     34-40. Jephthah came to Mizpeh unto his house, and, behold, his daughter came out to meet him with timbrels and with dances—The return of the victors was hailed, as usual, by the joyous acclaim of a female band (1Sa 18:6), the leader of whom was Jephthah's daughter. The vow was full in his mind, and it is evident that it had not been communicated to anyone, otherwise precautions would doubtless have been taken to place another object at his door. The shriek, and other accompaniments of irrepressible grief, seem to indicate that her life was to be forfeited as a sacrifice; the nature of the sacrifice (which was abhorrent to the character of God) and distance from the tabernacle does not suffice to overturn this view, which the language and whole strain of the narrative plainly support; and although the lapse of two months might be supposed to have afforded time for reflection, and a better sense of his duty, there is but too much reason to conclude that he was impelled to the fulfilment by the dictates of a pious but unenlightened conscience.
