2 Chronicles 19:8-10

8Moreover, in Jerusalem Jehoshaphat appointed certain Levites and priests and heads of families of Israel, to give judgment for the LORD and to decide disputed cases. They had their seat at Jerusalem. 9And he charged them: “Thus you shall do in the fear of the LORD, in faithfulness, and with your whole heart: 10whenever a case comes to you from your brothers who live in their cities, concerning bloodshed, law or commandment, statutes or rules, then you shall warn them, that they may not incur guilt before the LORD and wrath may not come upon you and your brothers. Thus you shall do, and you will not incur guilt.
