2 Chronicles 26:16-19

16But after Uzziah became powerful, his pride led to his downfall. He was unfaithful to the Lord his God, and entered the temple of the Lord to burn incense on the altar of incense.

17Azariah the priest with eighty other courageous priests of the Lord followed him in.

18They confronted King Uzziah and said, “It is not right for you, Uzziah, to burn incense to the Lord. That is for the priests, the descendants of Aaron, who have been consecrated to burn incense. Leave the sanctuary, for you have been unfaithful; and you will not be honored by the Lord God.”

19Uzziah, who had a censer in his hand ready to burn incense, became angry. While he was raging at the priests in their presence before the incense altar in the Lord’s temple, leprosy broke out on his forehead.
