2 Chronicles 26:17-20

17And Azariah the priest went in after him, and with him fourscore priests of the LORD, that were valiant men:

18and they withstood Uzziah the king, and said unto him, It pertaineth not unto thee, Uzziah, to burn incense unto the LORD, but to the priests the sons of Aaron, that are consecrated to burn incense: go out of the sanctuary; for thou hast trespassed; neither shall it be for thine honour from the LORD God.

19Then Uzziah was wroth; and he had a censer in his hand to burn incense; and while he was wroth with the priests, the leprosy brake forth in his forehead before the priests in the house of the LORD, beside the altar of incense.

20And Azariah the chief priest, and all the priests, looked upon him, and, behold, he was leprous in his forehead, and they thrust him out quickly from thence; yea, himself hasted also to go out, because the LORD had smitten him.
