'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
