18They took their stand against King Uzziah and said, “Uzziah, you have no right to offer incense to the LORD. Only the priests, the descendants of Aaron, are consecrated to burn incense. Leave the sanctuary, for you have acted unfaithfully; you will not receive honor from the LORD God.”
19Uzziah, with a censer in his hand to offer incense, was enraged. But while he raged against the priests in their presence in the house of the LORD before the altar of incense, leprosy broke out on his forehead.
