2 Chronicles 26:15-19

In Jerusalem he made machines of war invented by skillful workmen to be on the towers and the corners, for the purpose of shooting arrows and great stones. So his fame spread far, for he was marvelously helped until he was strong. Pride Is Uzziah’s Undoing

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

Then Azariah the priest entered after him, and with him eighty priests of the Lord, valiant men.

They opposed Uzziah the king 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 have been consecrated to burn incense. Leave the sanctuary, for you have been untrue and will have no honor from the Lord God.”

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