2 Chronicles 19:8-10

8Moreover in Jerusalem did Jehoshaphat set of the Levites, and of the priests, and of the chief of the fathers of Israel, for the judgment of Yhwh, and for controversies, when they returned to Jerusalem. 9And he charged them, saying, Thus shall ye do in the fear of Yhwh, faithfully, and with a perfect heart. 10And what cause soever shall come to you of your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and judgments, ye shall even warn them that they trespass not against Yhwh, and so wrath come upon you, and upon your brethren: this do, and ye shall not trespass.
