2 Chronicles 26:16; 2 Chronicles 26:19

16 But when he became strong, his heart was so proud that he acted corruptly, and he was unfaithful to the LORD his God, for he entered the temple of the LORD to burn incense on the altar of incense.

19 But Uzziah, with a censer in his hand for burning incense, was enraged; and while he was enraged with the priests, the leprosy broke out on his forehead before the priests in the house of the LORD , beside the altar of incense.
