30 And Jephthah took an oath to the Lord, and said, If you will give the children of Ammon into my hands, 31 Then whoever comes out from the door of my house, meeting me when I come back in peace from the children of Ammon, will be the Lord's and I will give him as a burned offering. 32 So Jephthah went over to the children of Ammon to make war on them; and the Lord gave them into his hands. 33 And he made an attack on them from Aroer all the way to Minnith, overrunning twenty towns, as far as Abel-cheramim, and put great numbers to the sword. So the children of Ammon were crushed before the children of Israel. 34 Then Jephthah came back to his house in Mizpah, and his daughter came out, meeting him on his way with music and with dances; she was his only child; he had no other sons or daughters. 35 And when he saw her he was overcome with grief, and said, Ah! my daughter! I am crushed with sorrow, and it is you who are the chief cause of my trouble; for I have made an oath to the Lord and I may not take it 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.
