2 Chronicles 19:8-11

8— And moreover in Jerusalem did Jehoshaphat set some of the Levites and priests, and of the chief fathers of Israel, for the judgment of Jehovah and for causes. — And they returned to Jerusalem. 9And he charged them saying, Thus shall ye do in the fear of Jehovah faithfully and with a perfect heart. 10And what cause soever comes to you of your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, ye shall even warn them that they trespass not against Jehovah, and so wrath come upon you and upon your brethren: this do and ye shall not trespass. 11And behold, Amariah the chief priest is over you in all matters of Jehovah, and Zebadiah the son of Ishmael, prince of the house of Judah, in all the king's matters; and ye have the Levites before you as officers. Be strong and do it, and Jehovah will be with the good.
