2 Chronicles 26:16-21 King James Version (KJV)
16 But when he was strong, his heart was lifted up to his destruction: for he transgressed against the Lord his God, and went into the temple of the Lord to burn incense upon the altar of incense.
17 And Azariah the priest went in after him, and with him fourscore priests of the Lord, that were valiant men:
18 And they withstood Uzziah the king, and said unto him, It appertaineth not unto thee, Uzziah, to burn incense unto the Lord, 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 honour from the Lord God.
19 Then Uzziah was wroth, and had a censer in his hand to burn incense: and while he was wroth with the priests, the leprosy even rose up in his forehead before the priests in the house of the Lord, from beside the incense altar.
20 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 from thence; yea, himself hasted also to go out, because the Lord had smitten him.
21 And Uzziah the king was a leper unto the day of his death, and dwelt in a several house, being a leper; for he was cut off from the house of the Lord: and Jotham his son was over the king's house, judging the people of the land.
2 Chronicles 26:16-21 New International Version (NIV)
16 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. 17 Azariah the priest with eighty other courageous priests of the Lord followed him in. 18 They confronted King Uzziah and said, “It is not right for you, Uzziah, to burn incense to the Lord. That is for the priests, the descendants of Aaron, who have been consecrated to burn incense. Leave the sanctuary, for you have been unfaithful; and you will not be honored by the Lord God.”
19 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[a] broke out on his forehead. 20 When Azariah the chief priest and all the other priests looked at him, they saw that he had leprosy on his forehead, so they hurried him out. Indeed, he himself was eager to leave, because the Lord had afflicted him.
21 King Uzziah had leprosy until the day he died. He lived in a separate house[b]—leprous, and banned from the temple of the Lord. Jotham his son had charge of the palace and governed the people of the land.
