2 Chronicles 26:16, 19

But after Uzziah became powerful, his pride led to his downfall. He was unfaithful to the LORD his God, and entered the temple of the LORD to burn incense on the altar of incense.

Uzziah, who had a censer in his hand ready to burn incense, became angry. While he was raging at the priests in their presence before the incense altar in the LORD’s temple, leprosy broke out on his forehead.
