2 Chronicles 19:8-10

8In Jerusalem also, Jehoshaphat appointed some of the Levites, priests and heads of Israelite families to administer the law of the Lord and to settle disputes. And they lived in Jerusalem. 9He gave them these orders: “You must serve faithfully and wholeheartedly in the fear of the Lord. 10In every case that comes before you from your people who live in the cities—whether bloodshed or other concerns of the law, commands, decrees or regulations—you are to warn them not to sin against the Lord; otherwise his wrath will come on you and your people. Do this, and you will not sin.
