The Canaanites were not the only ones who did not enjoy their wealth and money, for a similar fate was decreed for Korah. He had been the treasurer of Pharaoh, and possessed treasures so vast that he employed three hundred white mules to carry the keys of his treasures: but "let not the rich man boast of his riches," for Korah through his sin lost both life and property. Korah had obtained possession of his riches in the following way: When Joseph, during the lean years, through the sale of grain amassed great treasures, he erected three great buildings, one hundred cubits wide, one hundred cubits long, and one hundred cubits wide, one hundred high, filled them with money and delivered them to Pharaoh, being too honest to leave even five silver shekels of this money to his children. Korah discovered one of these three treasuries. On account of his wealth he became proud, and his pride brought about his fall.  He believed Moses had slighted him by appointing his cousin Elizaphan as chief of the Levite division of Kohathites. He said: "My grandfather had four sons, Amram, Ishar, Hebron, and Uzziel. Amram, as the firstborn, had privileges of which his sons availed themselves, for Aaron is high priest and Moses is king; but have not I, the son of Izhar, the second son of Kohath, the rightful claim to be prince of the Kohathites? Moses, however, passed me by and appointed Elizaphan, whose father was Uzziel, the youngest son of my grandfather. Therefore will I now stir up rebellion against Moses, and overthrow all institutions founded by him." Korah was far too wise a man to believe that God would permit success to a rebellion against Moses, and stand by indifferently, but the very insight that enabled him to look into the future became his doom. He saw with his prophetic eye that Samuel, a man as great as both Aaron and Moses together, would be one of his descendants; and furthermore that twenty-four descendants of his, inspired by the Holy Spirit, would compose psalms and sing them in the Temple. This brilliant future of his descendants inspired him with great confidence in his undertaking, for he thought to himself that God would not permit the father of such pious men to perish. His eye did not, however, look sharply enough into the future, or else he would also have known that his sons would repent of the rebellion against Moses, and would for this reason be deemed worthy of becoming the fathers of prophets and Temple singers, whereas he was to perish in this rebellion. 
The names of this unfortunate rebel corresponded to his deed and to his end. He was called Korah, "baldness," for through the death of his horde he caused a baldness in Israel. He was the son of Izhar, "the heat of the noon," because he caused the earth to be made to boil "like the heat of noon;" and furthermore he was designated as the son of Kohath, for Kohath signifies "bluntness," and through his sin he made "his children's teeth be set on edge." His description as the son of Levi, "conduct," points to his end, for he was conducted to hell. 
Korah, however, was not the only one who strove to overthrow Moses. With him were, first of all, the Reubenites, Dathan and Abiram, who well deserve their names, for the one signifies, "transgressor of the Divine law," and the other, "the obdurate." There were, furthermore, two hundred fifty men, who by their rank and influence belonged to the most prominent people in Israel; among them even the princes of the tribes. In the union of the Reubenites with Korah was verified the proverb, "Woe to the wicked, woe to his neighbor." For Korah, one of the sons of Kohath, had his station to the south of the Tabernacle, and as the Reubenites were also encamped there, a friendship was struck up between them, so that they followed him in his undertaking against Moses. 
The hatred Korah felt against Moses was still more kindled by his wife. When, after the consecration of the Levites, Korah returned home, his wife noticed that the hairs of his head and of his body had been shaved, and asked him who had done all this to him. He answered, "Moses," whereupon his wife remarked: "Moses hates thee and did this to disgrace thee." Korah, however, replied: "Moses shaved all the hair of his own sons also." But she said: "What did the disgrace of his own sons matter to him if he only felt he could disgrace thee? He was quite ready to make that sacrifice."  As at home, so also did Korah fare with others, for, hairless as he was, no one at first recognized him, and when people at last discovered who was before them, they asked him in astonishment who had so disfigured him. In answer to their inquiries he said, "Moses did this, who besides took hold of my hands and feet to lift me, and after he had lifted me, said, 'Thou art clean.' But his brother Aaron he adorned like a bride, and bade him take his place in the Tabernacle." Embittered by what they considered as insult offered him by Moses, Korah and his people exclaimed: "Moses is king, his brother did he appoint as high priest, his nephews as heads of the priests, he allots to the priest the heave offering and many other tributes."  Then he tried to make Moses appear ridiculous in the eyes of the people. Shortly before this Moses had read to the people the law of the fringes in the borders of their garments. Korah now had garments of purple made for the two hundred fifty men that followed him, all of whom were chief justices. Arrayed thus, Korah and his company appeared before Moses and asked him if they were required to attach fringes to the corners of these garments. Moses answered, "Yea." Korah then began this argument. "If," said he, "one fringe of purple suffices to fulfil this commandment, should not a whole garment of purple answered the requirements of the law, even if there be no special fringe of purple in the corners?" He continued to lay before Moses similar artful questions: "Must a Mezuzah be attached to the doorpost of the house filled with the sacred Books?" Moses answered, "Yea," Then Korah said: "The two hundred and seventy sections of the Torah are not sufficient, whereas the two sections attached to the door-post suffice!" Korah put still another question: "If upon a man's skin there show a bright spot, the size of half a bean, is he clean or is he unclean?" Moses: "Unclean." "And," continued Korah, "if the spot spread and cover all the skin of him, is he then clean or unclean?" Moses: "Clean." "Laws so irrational," said Korah, "cannot possibly trace their origin from God. The Torah that thou didst teach to Israel is not therefore God's work, but thy work, hence art thou no prophet and Aaron is no high priest!"
