In Israel the process would appear to have been similar, though much simpler. It was similar; for though there are radical differences between the Aryan and the Semitic mind which must not be overlooked, the former being more systematic and fond of logical arrangement than the latter, a great many of the things which are common to Moses and Manu are quite independent of race, and are due to the fact that both legislations were to regulate the lives of men at the same stage of social advancement. But Manu was much later than Moses. Indeed, as we now have them, the laws of Manu are as late as the post-Ezraite Judaic code, and in temper and tone these two codes very nearly resemble each other. Consequently the earlier codes of the Pentateuch are simpler than Manu. When Israel left Egypt, custom must have been almost alone the guide of life. Moses' task was to promulgate and force home his fundamental truths; in this view he must adopt and remodel the customary law so as to make it innocuous to the higher principles he introduced, or even to make it a vehicle for the popularising of them. So far as he made codes, he would make them with that end. Consequently he would take up mainly such prominent points as were most capable of being, or which most urgently needed to be, moralised, leaving all the rest to custom where it was harmless. This is the reason, too, most probably, why the earlier codes are so short and so unsystematic. They are selections which needed special attention, not complete codes covering the whole of life. In fact the form and contents of all the Old Testament codes can be accounted for only on this supposition. As the codes lengthen, they do so simply by taking up, in a modified or unmodified form, so much more of the custom; and under the pressure of Yahwistic ideas these selected codes became more and more weighted with spiritual significance and power.
That would seem to have been the process by which the inspired legislators of Israel did their work; and if it be so, some of the variations which are now taken to be certain indications of different ages and circumstances may simply represent local varieties of the same custom. Custom tends always to vary with the locality within certain narrow limits. It would be quite in accord with the general character of ancient customary law to believe that, provided the law was on the whole observed, there would be no inclination to insist upon excluding small local variations; and equally so that in a collection like the Pentateuch the custom of one locality should appear in one place, that of another in another. In that case, to insist that a certain sacrifice, for example, shall always consist of the same number of animals, and that any variation means a new and later legislation on the subject, is only to make a mistake. The discrepancy is made important only by applying modern English views of law to ancient law. Professor A. B. Davidson has shown in the Introduction to his _Ezekiel_ (p. liii.) that this latter was probably Ezekiel's view. "On any hypothesis of priority," he says, "the differences in details between him (_i.e._ Ezekiel) and the law (_i.e._ P) may be easiest explained by supposing that, while the sacrifices in general and the ideas which they expressed were fixed and current, the particulars, such as the kind of victims and the number of them, the precise quantity of meal, oil, and the like, were held non-essential and alterable when a change would better express the idea." The same principle would apply to the differences between Ezekiel and Deuteronomy, _e.g._ the omission of the feast of weeks and of the law of the offering of the firstlings of the flock. If so, then obviously Ezekiel must have thought that the previous ritual law was not meant to be as binding as we make it.
