2 Chronicles 26:16-20

MLV(i) 16 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. 17 And Azariah the priest went in after him and with him eighty priests of Jehovah, who were valiant men.
18 And they withstood Uzziah the king and said to him, It does not pertain to you, Uzziah, to burn incense to Jehovah, but to the priests the sons of Aaron who are consecrated to burn incense. Go out of the sanctuary. For you have trespassed, neither will it be for your honor from Jehovah God.
19 Then Uzziah was angry. And he had a censer in his hand to burn incense. And while he was angry with the priests, the leprosy broke forth in his forehead before the priests in the house of Jehovah, beside the altar of incense. 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 quickly from there. Yes, he himself also hastened to go out, because Jehovah had struck him.
