Uzziah ... transgressed against the LORD his God, and went into the temple of the LORD to burn incense upon the altar of incense.
And Azariah the priest went in after him, and with him fourscore priests of the LORD, that were valiant men:
And they withstood Uzziah the king, and said unto him, It appertaineth not unto thee, Uzziah, to burn incense unto the LORD, but to the priests. ....
And Azariah the chief priest, and all the priests, looked upon him, and, behold, he was leprous in his forehead, and they thrust him out from thence; yea, himself hasted also to go out, because the LORD had smitten him. 2 Chronicles 26:14-20
