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.

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.
