Jephthah’s vow was his promise, made before battle with the Ammonites, to offer to the Lord whatever first came from his house to meet him if he returned victorious. His daughter was the first to greet him, making the vow a source of grief and tragedy.
The narrative records Jephthah’s anguish, his daughter’s acceptance, and her request for two months to bewail her maidenhood. The supplied interpretations differ: some understand an actual burnt offering, while another concludes that she was devoted to lifelong celibacy.
The vow is presented as the mistaken act of a rugged chieftain rather than something pleasing to God. The material emphasizes that such sacrifices were contrary to the Mosaic law.
