2 Chronicles 19
8 Ref Moreover in Jerusalem did Jehoshaphat set of the Levites and the priests, and of the heads of the fathers' [houses] of Israel, for the judgment of Yahweh, and for controversies. They returned to Jerusalem.
9 Ref He charged them, saying, Thus shall you do in the fear of Yahweh, faithfully, and with a perfect heart.
10 Ref Whenever any controversy shall come to you from your brothers who dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, you shall warn them, that they not be guilty towards Yahweh, and so wrath come on you and on your brothers: this do, and you shall not be guilty.
11 Ref Behold, Amariah the chief priest is over you in all matters of Yahweh; and Zebadiah the son of Ishmael, the ruler of the house of Judah, in all the king's matters: also the Levites shall be officers before you. Deal courageously, and Yahweh be with the good.
