The king of Ammon refused Jephthah's offer to negotiate. He claimed the land bounded by the Arnon, the Jabbok and Jordan as his own and demanded that it should be peaceably given up to him. In reply Jephthah denied the claim. It was the Amorites, he said, who originally held that part of Syria. Sihon who was defeated in the time of Moses was not an Ammonite king, but chief of the Amorites. Israel had by conquest obtained the district in dispute, and Ammon must give place.
The full account given of these messages sent by Jephthah shows a strong desire on the part of the narrator to vindicate Israel from any charge of unnecessary warfare. And it is very important that this should be understood, for the inspiration of the historian is involved. We know of nations that in sheer lust of conquest have attacked tribes whose land they did not need, and we have read histories in which wars unprovoked and cruel have been glorified. In after times the Hebrew kings brought trouble and disaster on themselves by their ambition. It would have been well if David and Solomon had followed a policy like Jephthah's rather than attempted to rival Assyria and Egypt. We see an error rather than a cause of boasting when David put garrisons in Syria of Damascus: strife was thereby provoked which issued in many a sanguinary war. The Hebrews should never have earned the character of an aggressive and ambitious people that required to be kept in check by the kingdoms around. To this nation, a worldly nation on the whole, was committed a spiritual inheritance, a spiritual task. Is it asked why being worldly the Hebrews ought to have fulfilled a spiritual calling? The answer is that their best men understood and declared the Divine will, and they should have listened to their best men. Their fatal mistake was, as Christ showed, to deride their prophets, to crush and kill the messengers of God. And many other nations likewise have missed their true vocation being deluded by dreams of vast empire and earthly glory. To combat idolatry was indeed the business of Israel and especially to drive back the heathenism that would have overwhelmed its faith; and often this had to be done with an earthly sword because liberty no less than faith was at stake. But a policy of aggression was never the duty of this people.
The temperate messages of the Hebrew chief to the king of Ammon proved to be of no avail: war alone was to settle the rival claims. And this once clear Jephthah lost no time in preparing for battle. As one who felt that without God no man can do anything, he sought assurance of divine aid; and we have now to consider the vow which he made, ever interesting on account of the moral problem it involves and the very pathetic circumstances which accompanied its fulfilment.
The terms of the solemn engagement under which Jephthah came were these:--"If Thou wilt indeed deliver the children of Ammon into mine hand, then it shall be that whatsoever" (Septuagint and Vulgate, "_whosoever_") "cometh forth of the doors of my house to meet me when I return in peace from the children of Ammon shall be the Lord's, and I will offer it (otherwise, _him_) for a burnt offering." And here two questions arise; the first, what he could have meant by the promise; the second, whether we can justify him in making it. As to the first, the explicit designation to God of whatever came forth of the doors of his house points unmistakably to a human life as the devoted thing. It would have been idle in an emergency like that in which Jephthah found himself, with a hazardous conflict impending that was to decide the fate of the eastern tribes at least, to anticipate the appearance of an animal, bullock, goat or sheep, and promise that in sacrifice. The form of words used in the vow cannot be held to refer to an animal. The chief is thinking of some one who will express joy at his success and greet him as a victor. In the fulness of his heart he leaps to a wild savage mark of devotion. It is a crisis alike for him and for the people and what can he do to secure the favour and help of Jehovah? Too ready from his acquaintance with heathen sacrifices and ideas to believe that the God of Israel will be pleased with the kind of offerings by which the gods of Sidon and Aram were honoured, feeling himself as the chief of the Hebrews bound to make some great and unusual sacrifice, he does not promise that the captives taken in war shall be devoted to Jehovah, but some one of his own people is to be the victim. The dedication shall be all the more impressive that the life given up is one of which he himself shall feel the loss. A conqueror returning from war would, in ordinary circumstances, have loaded with gifts the first member of his household who came forth to welcome him. Jephthah vows to give that very person to God. The insufficient religious intelligence of the man, whose life had been far removed from elevating influences, this once perceived--and we cannot escape from the facts of the case--the vow is parallel to others of which ancient history tells. Jephthah expects some servant, some favourite slave to be the first. There is a touch of barbaric grandeur and at the same time of Roman sternness in his vow. As a chief he has the lives of all his household entirely at his disposal. To sacrifice one will be hard, for he is a humane man; but he expects that the offering will be all the more acceptable to the Most High. Such are the ideas moral and religious from which his vow springs.
