DEUT. vi. 6-25
Those great verses, Deut. vi. 4, 5, form the central truth of the book. Everything else in it proceeds from and is informed by them, and they are dwelt upon and enforced with a clear perception of their radical importance. There is something of the joy of discovery in the way in which the unity of Yahweh and exclusive love to Him are insisted upon, not only in verses 6-25 of this chapter, but in xi. 13-20. The same strongly worded demand to lay to heart Yahweh's command to love Him and Him only, and to teach it strenuously to their children--to make it "a sign upon their hand," and "as a frontlet between their eyes"--is found in both passages. It is worthy of remark also that nearly the same words are found in Exod. xiii. 9, 16. Presumably on account of this, some have ascribed that section of Exodus to the author of Deuteronomy. But both Dillmann and Driver ascribe these passages to J and E, and with good reason. Indeed, apart from the purely literary grounds for thinking that these formulas were first used by the earlier writers and were copied by the author of Deuteronomy, another line of argument points in the same direction. In Exodus the thing to be remembered and taught to the children was the meaning and origin of the Passover and the consecration of the firstborn, _i.e._ the meaning and origin of some of their ritual institutions. Here in Deuteronomy, on the contrary, that which is to be written on the heart and taught to the children is moral and spiritual truth about God, and love to God. Now the probable explanation of this likeness and difference is, not that the author of Deuteronomy, after using this insistive phrase only of high spiritual truths in his own book, inserted it in Exodus with regard to mere institutions of the cultus; rather, the writers of Exodus had used it of that which was important in their day, and the Deuteronomist borrowed it from them to emphasise his own most cherished revelation. In the earlier stages of a religious movement, the establishment of institutions which shall embody and perpetuate religious truth, is one of the first necessities. It has become a commonplace of Christian defence, for example, that Baptism and the Lord's Supper were made the most successful vehicles for conveying fundamental Christian truth, and that the celebration of these two rites from the first days even until now is one of the most convincing proofs of the continuity of Christianity. Naturally, therefore, the establishment of the Passover was specially marked out as the _palladium_ of Israelite religion in the earlier days. But in the time after Isaiah, when Deuteronomy was written, the institutions needed no longer such insistence. They had indeed become so important to the people that the mere observance of them threatened to become a substitute for religious and even moral feeling. The Deuteronomist's great message was, consequently, a reiteration of the prophetic truths as to the supremacy of the spiritual; and for the object of the warm exhortation of the earlier writings he substituted the proclamation of Yahweh's oneness, and of His demand for His people's love. This seems a reasonable and probable explanation of the facts as we find them. If true, it is a proof that the need of ritual institutions, and the danger of unduly exalting them, was not peculiar to post-exilic times. In principle the temptation was always present; and as living faith rose and fell it came into operation, or was held in abeyance, throughout the whole of Israel's history. Hence the mention of this kind of formalism or the denunciation of it must be very cautiously used as a criterion by which to date any Scriptural writings.
It is therefore with a full consciousness of its fundamental importance that the author of Deuteronomy follows the great passage chapter vi. 4, 5, with this solemn and inspiring exhortation. It is from no mere itch for religious improvement of the occasion that he presses home his message thus. Nor is it love for the mere repetition of an ancient formula of exhortation that dictates its use. He knew and understood the work of Moses, and felt that the moulding power in Israel's life as a nation, the unifying element in it, had been the religion of Yahweh. Whatever else may have been called in question, it has never been doubted that the salt which kept the political and social life of the people from rotting through many centuries was the always advancing knowledge of God. At each great crisis of Israel's history the religion of Yahweh had met the demands for direction, for inspiration, for uplifting which were made upon it. With Protean versatility it had adapted itself to every new condition. In all circumstances it had provided a lamp for the feet and a light for the path of the faithful; and in meeting the needs of generation after generation it had revealed elements of strength and consolation which, without the commentary of experience, could never have been brought out. Now the author of Deuteronomy felt that in these short sentences the high-water mark of Israelite religion so far had been reached, and that in renewing the work of Moses, and adapting it to his own time, the principles here enunciated must be the main burden of his message. Further progress depended, he obviously felt, upon the absorption and assimilation of these truths by his people, and he felt he must provide for the perpetuation of them in that better time he was preparing for. This he did by providing for the religious education of the young. Whatever else Israel had gained it had been careful to hand on from generation to generation. The land flowing with milk and honey was still in the possession of the descendants of the first conquerors. The literature, the science, the wisdom that the fathers had gathered, had been carefully passed down to the children; and a precious deposit of enriching experience in the form of history had reached to the elect even among the common people, as the example of Amos shows. But the most valuable heritage of Israel was that continually growing deposit of religious truth which had been the life-blood of its master spirits. From generation to generation the noblest men in the nation, those most sensitive to the touch of the Divine, had been casting soundings into the great deep of the hidden purposes of God. With sore travail of both mind and spirit, they had found solutions of the great problems which no living soul can escape. These were no doubt more or less partial, but they were sufficient for their day, and were always in the line of the final answer. As the sum of experience widened, the scope of the solutions widened also, and in the course of Providence these issued in a conception of God which elsewhere was never approached. This of all national treasures was the most priceless, and to preserve and hand on this was simply to keep the national soul alive. Compared with this, every other heritage from the past was as nothing; and so, with a simple directness which must amaze the legislators of modern states, the inspired lawgiver arranged for a religious education.
