II Chronicles 26:16-19

But when he was strong his heart was lifted up, to his destruction, for he transgressed against the LORD his God by entering the temple of the LORD to burn incense on the altar of incense. So Azariah the priest went in after him, and with him were eighty priests of the LORD—valiant men. And 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.” Then 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.
