After the death of the two hundred and fifty followers of Korah, who perished at the offering of incense, Eleazar, the son of Aaron, was ordered "to take up the censers out of the burning," in which the souls, not the bodies of the sinners were burned, that out of these brasen plates he made a covering for the altar. Eleazar, and not his father, the high priest, received this commission, for God said: "The censer brought death upon two of Aaron's sons, therefore let the third now fetch forth the censer and effect expiation for the sinners."
The covering of the altar fashioned out of the brass of these censers was "to be a memorial unto the children of Israel, to the end that no stranger, which is not of the seed of Aaron, come near to burn incense before the Lord." Such a one was not, however, to be punished like Korah and his company, but in the same way as Moses had once been punished by God, with leprosy. This punishment was visited upon king Uzziah, who tried to burn incense in the Temple, asserting that it was the king's task to perform the service before the King of all.
The heavens hastened to the scene to consume him, just as the celestial fire had once consumed the two hundred and fifty men, who had wrongfully assumed the rights of priesthood; the earth strove to swallow him as it had once swallowed Korah and his company. But a celestial voice announced: "Upon none save Korah and his company came punishments like these, upon no others. This man's punishment shall be leprosy." Hence Uzziah became a leper.
