But besides these two classes of laws and customs there must have been a number which were so bound up with the lower religion that they could not be adopted. They would either be obstructive of the new ideas, or they would be positively hostile to them; for on any supposition heathenism of various sorts was largely mingled with the religion of the Israelite people before their deliverance, and even after it. To sift these out, and to replace them by others more in accord with the will of Yahweh as now revealed, must have been the chief work of the lawgiver. In that more or less protracted period before Israel came to Sinai, during which Moses burdened himself with judging the people personally, he must have been doing this work. His reflections in the wilderness had doubtless prepared him for it. In a mind like his, the fruitful principles received by the inspiration of the Almighty could not be merely passively held. Like St. Paul in his Arabian sojourn, we must believe that Moses in Midian would work out the results of these principles in many directions; and when he led Israel forth, he must have been clearly conscious of changes that were indispensable. But it needed close every-day contact with the life of the people to bring out all the incompatibilities which he would have to remove. Every day unexpected complications would arise; and the people at any rate, if Moses himself be supposed to be raised by his inspiration above the needs of experience, would be able to receive the instruction they needed only in concrete examples, here a little and there a little. When they came to "seek Yahweh" in any matter which perplexed them, Moses gave them Yahweh's mind on the subject; and each decision tended to purify and render innocuous to their higher life some department of public or private affairs. Every day at that early time must have been a day of instruction how to apply the principles of the higher faith just revived. The better minds among the chiefs were thereby trained to an appreciation of the new point of view; and when Jethro suggested that the burden of this work should be divided, quite a sufficient number were found prepared to carry it on. After this it must have gone on with tenfold speed, and we may believe that when Sinai was reached the preliminaries on the human side to the great revelation had been thoroughly elaborated. The Divine presence had been with Moses day by day, judging, deciding, inspiring in all their individual concerns as well as in their common affairs. But that would only bring out more clearly the extent of the reformation that remained to be wrought; doubtless too it had revealed the dulness of heart in regard to the Divine which has always characterised the mass of men. The need for a more complete revelation, a more extended and detailed legislation on the new basis, must have been greatly felt. In the great scene at Sinai, a scene so strange and awe-inspiring that to the latest days of Israel the memory of it thrilled every Israelite heart and exalted every Israelite imagination, this need was adequately met.
In connection with it Moses rose to new heights of intimacy with the Divine. What he had already done was ratified, and in the Decalogue the great lines of moral and social life were marked out for the people. But the most remarkable thing to us, in the narrative of the circle of events which made the mountain of the law for ever memorable, is the sublimity attributed to the character of Moses. From the day when he smote the Egyptian, at every glimpse we have of him we find him always advancing in power of character. The shepherd of Midian is nobler, less self-assertive, more overawed by communion with God, than the son of Pharaoh's daughter, noble as he was. Again, the religious reformer, the popular leader, who needs the very insistence of God to make him lead, who speaks for God with such courageous majesty, who teaches, inspires, and manages a turbulent nation with such conspicuous patience, self-repression, and success, is greatly more impressive than the Moses of Midianite days. But it is here, at Sinai, that his rank among the leaders of men is fixed for ever. To the people of that time God was above all things terrible; and when they came to the mount and found that "there were thunders and lightnings and a thick cloud upon the mount, and the voice of the trumpet exceeding loud," they could only tremble. Their very fear made it impossible for them to understand what God desired to reveal concerning Himself. But in Moses love had cast out fear. Even to him, doubtless, the darkness was terrible, because it expressed only too well the mystery which enwrapped the end of the Divine purposes of which he alone had seen the beginnings; even his mind must have been clouded thick with doubts as to whither Yahweh was leading him and his people; yet he went boldly forth to seek God, venturing all upon that errand.
