2 Chronicles 26:14-21

And Uzziah prepared for them, even for all the host, shields, and spears, and helmets, and coats of mail, and bows, and stones for slinging. And he made in Jerusalem engines, invented by skilful men, to be on the towers and upon the battlements, wherewith to shoot arrows and great stones. And his name spread far abroad; for he was marvellously helped, till he was strong. But when he was strong, his heart was lifted up, so that he did corruptly, and he trespassed against Jehovah his God; for he went into the temple of Jehovah to burn incense upon the altar of incense. And Azariah the priest went in after him, and with him fourscore priests of Jehovah, that were valiant men: and they withstood Uzziah the king, and said unto him, It pertaineth not unto thee, Uzziah, to burn incense unto Jehovah, but to the priests the sons of Aaron, that are consecrated to burn incense: go out of the sanctuary; for thou hast trespassed; neither shall it be for thine honor from Jehovah God. Then Uzziah was wroth; and he had a censer in his hand to burn incense; and while he was wroth with the priests, the leprosy brake forth in his forehead before the priests in the house of Jehovah, beside the altar of incense. And Azariah the chief priest, and all the priests, looked upon him, and, behold, he was leprous in his forehead, and they thrust him out quickly from thence; yea, himself hasted also to go out, because Jehovah had smitten him. And Uzziah the king was a leper unto the day of his death, and dwelt in a separate house, being a leper; for he was cut off from the house of Jehovah: and Jotham his son was over the king’s house, judging the people of the land.
