2 Chronicles 26:16-19

But when he had become powerful, he also became proud, which led to his downfall. He sinned against the LORD his God by entering the sanctuary of the LORD’s Temple and personally burning incense on the incense altar. Azariah the high priest went in after him with eighty other priests of the LORD, all brave men. They confronted King Uzziah and said, “It is not for you, Uzziah, to burn incense to the LORD. That is the work of the priests alone, the descendants of Aaron who are set apart for this work. Get out of the sanctuary, for you have sinned. The LORD God will not honor you for this!” Uzziah, who was holding an incense burner, became furious. But as he was standing there raging at the priests before the incense altar in the LORD’s Temple, leprosy suddenly broke out on his forehead.
