There is a mustering at Kadesh of the scattered tribes, for now the end of the period of wandering approaches, and the generation that has been disciplined in the wilderness must prepare for a new advance. The spies who searched Canaan were sent from Kadesh (xiii. 26), to which, in the second year from the exodus, the tribes had penetrated. Now, in the first month of the fortieth year it would seem, Kadesh is again the headquarters. The adjacent district is called the desert of Zin. Eastward, across the great plain of the Arabah, reaching from the Dead Sea to the Elanitic Gulf, are the mountains of Seir, the natural rampart of Edom. To the head of the Gulf at Elath the distance is some eighty miles in a straight line southward; to the southern end of the Dead Sea it is about fifty miles. Kadesh is almost upon the southern border of Canaan; but the way of the Negeb is barred by defeat, and Israel must enter the Promised Land by another route. In preparation for the advance the tribes gather from the wadies and plateaus in which they have been wandering, and at Kadesh or near it the earlier incidents of this chapter occur. First among them is the death of Miriam. She has survived the hardships of the desert and reached a very great age. Her time of influence and vigour past, all the joys of life now in the dim memories of a century, she is glad, no doubt, when the call comes. It was her happiness once to share the enthusiasm of Moses and to sustain the faith of the people in their leader and in God. But any service of this kind she could render has been left behind. For some time she has been able only now and then with feeble steps to move to the tent of meeting that she might assure herself of the welfare of Moses. The tribes will press on to Canaan, but she shall never see it.
