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.
      1. There are several good lessons to be learnt out of this story. (1.) That there may be remainders of distrust and doubting even in the hearts of true and great believers. Jephthah had reason enough to be confident of success, especially when he found the Spirit of the Lord come upon him, and yet, now that it comes to the settling, he seems to hesitate (Judges 11:30; Judges 11:30): If thou wilt without fail deliver them into my hand, then I will do so and so. And perhaps the snare into which his vow brought him was designed to correct the weakness of his faith, and a fond conceit he had that he could not promise himself a victory unless he proffered something considerable to be given to God in lieu of it. (2.) That yet it is very good, when we are in the pursuit or expectation of any mercy, to make vows to God of some instance of acceptable service to him, not as a purchase of the favour we desire, but as an expression of our gratitude to him and the deep sense we have of our obligations to render according to the benefit done to us. The matter of such a singular vow (Leviticus 27:2) must be something that has a plain and direct tendency either to the advancement of God's glory, and the interests of his kingdom among men, or to the furtherance of ourselves in his service, and in that which is antecedently our duty. (3.) That we have great need to be very cautious and well advised in the making of such vows, lest, by indulging a present emotion even of pious zeal, we entangle our own consciences, involve ourselves in perplexities, and are forced at last to say before the angel that it was an error,Ecclesiastes 5:2-6. It is a snare to a man hastily to devour that which is holy, without due consideration quid valeant humeri, quid ferre recusent--what we are able or unable to effect, and without inserting the needful provisos and limitations which might prevent the entanglement, and then after vows to make the enquiry which should have been made before, Proverbs 20:25. Let Jephthah's harm be our warning in this matter. See Deuteronomy 23:22. (4.) That what we have solemnly vowed to God we must conscientiously perform, if it be possible and lawful, though it be ever so difficult and grievous to us. Jephthah's sense of the powerful obligation of his vow must always be ours (Judges 11:35; Judges 11:35): "I have opened my mouth unto the Lord in a solemn vow, and I cannot go back," that is, "I cannot recall the vow myself, it is too late, nor can any power on earth dispense with it, or give me up my bond." The thing was my own, and in my own power (Acts 5:4), but now it is not. Vow and pay,Psalms 76:11. We deceive ourselves if we think to mock God. If we apply this to the consent we have solemnly given, in our sacramental vows, to the covenant of grace made with poor sinners in Christ, what a powerful argument will it be against the sins we have by those vows bound ourselves out from, what a strong inducement to the duties we have hereby bound ourselves up to, and what a ready answer to every temptation! "I have opened my mouth to the Lord, and I cannot go back; I must therefore go forward. I have sworn, and I must, I will, perform it. Let me not dare to play fast and loose with God." (5.) That it well becomes children obediently and cheerfully to submit to their parents in the Lord, and particularly to comply with their pious resolutions for the honour of God and the keeping up of religion in their families, though they be harsh and severe, as the Rechabites, who for many generations religiously observed the commands of Jonadab their father in forbearing wine, and Jephthah's daughter here, who, for the satisfying of her father's conscience, and for the honour of God and her country, yielded herself as one devoted (Judges 11:36; Judges 11:36): "Do to me according to that which hath proceeded out of thy mouth; I know I am dear to thee, but am well content that God should be dearer." The father might disallow any vow made by the daughter (Numbers 30:5), but the daughter could not disallow or disannul, no, not such a vow as this, made by the father. This magnifies the law of the fifth commandment. (6.) That our friends' grievances should be our griefs. Where she went to bewail her hard fate the virgins, her companions, joined with her in her lamentations, Judges 11:38; Judges 11:38. With those of her own sex and age she used to associate, who no doubt, now that her father had on a sudden grown so great, expected, shortly after his return, to dance at her wedding, but were heavily disappointed when they were called to retire to the mountains with her and share in her griefs. Those are unworthy the name of friends that will only rejoice with us, and not weep with us. (7.) That heroic zeal for the honour of God and Israel, though alloyed with infirmity and indiscretion, is worthy to be had in perpetual remembrance. It well became the daughters of Israel by an annual solemnity to preserve the honourable memory of Jephthah's daughter, who made light even of her own life like a noble heroine, when God had taken vengeance on Israel's enemies, Judges 11:36; Judges 11:36. Such a rare instance of one that preferred the public interest before life itself was never to be forgotten. Her sex forbade her to follow to the war, and so to expose her life in battle, in lieu of which she hazards it much more (and perhaps apprehended that she did so, having some intimation of his vow, and did it designedly; for he tells her, Judges 11:35; Judges 11:35, Thou hast brought me very low) to grace his triumphs. So transported was she with the victory as a common benefit that she was willing to be herself offered up as a thank-offering for it, and would think her life well bestowed when laid down on so great an occasion. She thinks it an honour to die, not as a sacrifice of atonement for the people's sins (that honour was reserved for Christ only), but as a sacrifice of acknowledgment for the people's mercies. (8.) From Jephthah's concern on this occasion, we must learn not to think it strange if the day of our triumphs in this world prove upon some account or other the day of our griefs, and therefore must always rejoice with trembling; we hope for a day of triumph hereafter which will have no alloy.
