What does 2 Chronicles 19:10 mean?

'Whenever a case comes to you from your fellow citizens in their towns - whether it's about murder, law, commandments, rules, or regulations - you must warn them not to sin against the Lord. If you don't, God's anger will come on you and your people. So do your job well.' 2 Chronicles 19:10 - Modern Text Bible
