The number of the stations at which Israel encamped in the course of forty years can scarcely be taken as representing the number of changes from dwelling to dwelling any pilgrim through this world shall have to make. But if we think of halting-places and movements of thought, we shall have a fruitful parallel. From the twentieth to the sixtieth year--may we not say?--is the time of journeying that takes the mind from its first freedom to comparative rest. Not far on the Divine law-giving impresses itself on the conscience; and hence a direct road may appear to lead into the peace of obedience. But the stations successively reached, Kibroth-hattaavah, Hazeroth, Rithmah, and the rest, represent each a peculiar difficulty encountered, a barrier to our steady progress towards the settled mind. St. Paul indicates one he found when he says: "I had not known coveting, except the law had said, Thou shalt not covet." Another halt is imposed when it is found that the law appears to forbid what is according to nature; still another when obedience requires separation from those who have been valued friends and pleasant companions. These hindrances left behind as the soul, still confiding and hopeful, is urged on towards the goal, a great trial like that of Kadesh follows. We are not far from the frontier of promise; and anticipations are formed of many delights for heart and life. Is not obedience to bring felicity, an easy salvation from doubt and fear? But it becomes plain that there are enemies to faith and peace beyond the border as well as in the region already crossed. Complete conformity to the Divine will has not been achieved. Will it ever be achieved? We begin to doubt the result of law-keeping. There is perhaps a backward look to Sinai, implying a question whether God spoke there, or beyond Sinai, to the old traditional way of life. And so another term of difficult inquiry begins.
