Secondly, as to the so‐called _laws given to Moses on Sinai_.(146) Much has been said about these. The distinction claimed for them by some scholars, viz. that they were never contested, is not tenable, considering that there prevailed much difference of opinion about some of them. Nor is the theory that they were ancient religious usages, dating from time immemorial, entirely satisfactory. For though the fact may be true in itself, this could not have justified the Rabbis in calling them all Sinaitic laws, especially when they were aware that not a few of them were contested by certain of their colleagues, a thing that would have been quite impossible if they had a genuine claim to Mosaic authority. But if we understand Weiss rightly these laws are only to be considered as a specimen of the whole of the Oral Law, which was believed to emanate, both in its institutional and in its expository part, from the same authority. The conviction was firmly held that everything wise and good, be it ethical or ceremonial in its character, whose effect would be to strengthen the cause of religion, was at least potentially contained in the Torah, and that it only required an earnest religious mind to find it there. Hence the famous adage that “everything which any student will teach at any future time was already communicated to Moses on Mount Sinai”; or the injunction that any acceptable truth, even if discovered by an insignificant man in Israel, should be considered as having the authority of a great sage or prophet, or even of Moses himself. The principle was that the words of the Torah are “fruitful and multiply.” It will probably be said that the laws of clean and unclean, and such like, have proved rather too prolific; but if we read Weiss carefully, we shall be reminded that it was by the same process of propagation that the Rabbis developed from Deut. xxii. 8, a whole code of sanitary and police‐ laws which could even now be studied with profit; from the few scanty civil laws in Exod. xxi., a whole _corpus juris_, which might well excite the interest and the admiration of any lawyer; and from the words “And thou shalt teach them diligently unto thy children,” a complete school‐ system on the one hand, and on the other the _résumé_ of a liturgy that appears to have sufficed for the spiritual needs of more than fifty generations of Israelites.
