17 Then Azariah the priest, along with eighty brave priests of the LORD, went in after him.
18 They 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.”

21 So King Uzziah was a leper until the day of his death. He lived in isolation, leprous and cut off from the house of the LORD, while his son Jotham had charge of the royal palace to govern the people of the land.
