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.
