2 Chronicles 26:17-20

17So Azariah the priest went in after him, and with him were eighty priests of the Lord—valiant men.

18And they withstood King Uzziah, and said to him, “It is not for you, Uzziah, to burn incense to the Lord, but for the priests, the sons of Aaron, who are consecrated to burn incense. Get out of the sanctuary, for you have trespassed! You shall have no honor from the Lord God.”

19Then Uzziah became furious; and he had a censer in his hand to burn incense. And while he was angry with the priests, leprosy broke out on his forehead, before the priests in the house of the Lord, beside the incense altar.

20And Azariah the chief priest and all the priests looked at him, and there, on his forehead, he was leprous; so they thrust him out of that place. Indeed he also hurried to get out, because the Lord had struck him.
