2 Chronicles 26:14-21

Moreover, Uzziah prepared shields, spears, helmets, body armor, bows, and sling stones for the entire army. In Jerusalem he made machines of war invented by skillful men to be put on the towers and on the [corner] battlements for the purpose of shooting arrows and large stones. And his fame spread far, for he was marvelously helped until he was strong. But when Uzziah became strong, he became so proud [of himself and his accomplishments] that he acted corruptly, and he was unfaithful and sinned against the LORD his God, for he went into the temple of the LORD to burn incense on the altar of incense. [Num 3:38] Then Azariah the priest went in after him, and with him eighty priests of the LORD, men of courage. They opposed 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 have been consecrated to burn incense. Get out of the sanctuary, for you have been unfaithful and will have no honor from the LORD God.” Then Uzziah, with a censer in his hand to burn incense, was enraged; and while he was enraged with the priests, leprosy broke out on his forehead before the priests in the house of the LORD, beside the incense altar. As Azariah the chief priest and all the priests looked toward him, behold, he was leprous on his forehead; and they hurried him out of there, and he also hurried to get out because the LORD had stricken him. King Uzziah was a leper to the day of his death; and, being a leper, he lived in a separate house, for he was excluded from the house of the LORD. And his son Jotham took charge of the king’s household, judging and governing the people of the land.
