2 Chronicles 26:16–21
16 But when rhe was strong, she grew proud, to his destruction. For he was unfaithful to the Lord his God and entered the temple of the Lord to burn incense on the altar of incense. 17 But tAzariah the priest went in after him, with eighty priests of the Lord who were men of valor, 18 and they withstood King Uzziah and said to him, u“It is not for you, Uzziah, to burn incense to the Lord, vbut for the priests, the sons of Aaron, who are consecrated to burn incense. Go out of the sanctuary, for you have done wrong, and it will bring you no honor from the Lord God.” 19 Then Uzziah was angry. Now he had a censer in his hand to burn incense, and when he became angry with the priests, wleprosy1 broke out on his forehead in the presence of the priests in the house of the Lord, by the altar of incense. 20 And Azariah the chief priest and all the priests looked at him, and behold, he was leprous in his forehead! And they rushed him out quickly, and he himself hurried to go out, because the Lord had struck him. 21 xAnd King Uzziah was a leper to the day of his death, and being a leper lived yin a separate house, for he was excluded from the house of the Lord. And Jotham his son was over the king’s household, governing the people of the land.
Leprosy was a term for several skin diseases; see Leviticus 13
