2 Chronicles 26:18 NIV

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.”
