God "taketh the wise in their own craftiness." He had long before this decreed that Moses die in the desert, and Moses' offense in Kadesh was only a pretext God employed that He might not seem to be unjust. But He gave to Moses himself the true reason why He did not permit him to enter the promised land, saying: "Would it perchance redound to thy glory if thou wert to lead into the land a new generation after thou hadst led out of Egypt the sixty myriads and buried them in the desert?
People would declare that the generation of the desert has no share in future world, therefore stay with them, that at their head thou mayest after the Resurrection enter the promised land." Moses now said to God: "Thou hast decreed that I die in the desert like the generation of the desert that angered Thee. I implore Thee, write in Thy Torah wherefore I have been thus punished, that future generations may not say I had been like the generations of the desert."
God granted this wish, and in several passages of the Scriptures set forth what had really been the offense on account of which Moses had been prohibited from entering the promised land. It was due only to the transgression at the rock in Kadesh, where Moses failed to sanctify God in the eyes of the children of Israel; and God was sanctified by allowing justice to take its course without respect of persons, and punishing Moses.
Hence this place was called Kadesh, "sanctity," and En Mishpat, "fountain of justice," because on this spot judgement was passed upon Moses, and by this sentence God's name was sanctified.
