30 Jephthah vowed a vow to Yahweh, and said, “If you will indeed deliver the children of Ammon into my hand, 31 then it shall be, that whatever comes forth from the doors of my house to meet me, when I return in peace from the children of Ammon, it shall be Yahweh’s, and I will offer it up for a burnt offering.” 32 So Jephthah passed over to the children of Ammon to fight against them; and Yahweh delivered them into his hand. 33 He struck them from Aroer until you come to Minnith, even twenty cities, and to Abelcheramim, with a very great slaughter. So the children of Ammon were subdued before the children of Israel. 34 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. 35 It happened, when he saw her, that he tore his clothes, and said, “Alas, my daughter! You have brought me very low, and you are one of those who trouble me; for I have opened my mouth to Yahweh, and I can’t go back.”

Several important lessons are to be learned from Jephthah's vow. 1. There may be remainders of distrust and doubting, even in the hearts of true and great believers. 2. Our vows to God should not be as a purchase of the favour we desire, but to express gratitude to him. 3. We need to be very well-advised in making vows, lest we entangle ourselves. 4. What we have solemnly vowed to God, we must perform, if it be possible and lawful, though it be difficult and grievous to us. 5. It well becomes children, obediently and cheerfully to submit to their parents in the Lord. It is hard to say what Jephthah did in performance of his vow; but it is thought that he did not offer his daughter as a burnt-offering. Such a sacrifice would have been an abomination to the Lord; it is supposed she was obliged to remain unmarried, and apart from her family. Concerning this and some other such passages in the sacred history, about which learned men are divided and in doubt, we need not perplex ourselves; what is necessary to our salvation, thanks be to God, is plain enough. If the reader recollects the promise of Christ concerning the teaching of the Holy Spirit, and places himself under this heavenly Teacher, the Holy Ghost will guide to all truth in every passage, so far as it is needful to be understood.
