What does 2 Chronicles 26:16 mean?

But when Uzziah became strong, he grew proud, and that pride led to his downfall. He ignored God’s ways and went into the temple to burn incense on the altar, something only priests were allowed to do. 2 Chronicles 26:16 - Modern Text Bible

(Uzziah’s pride made him overstep his boundaries, disrespecting God’s instructions about worship.)
