What does 2 Chronicles 30:8 mean?

Don’t be stubborn like your ancestors were. Instead, open your hearts to the Lord and come back to his sanctuary, the place he set apart forever. Serve the Lord your God, and maybe he’ll turn his anger away from you. 2 Chronicles 30:8 - Modern Text Bible

(Hezekiah urges the people not to repeat the mistakes of their ancestors, who resisted God. He invites them to return to God’s presence and serve him, hoping God will show mercy.)
