Haggai

If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within thy gates: then shalt thou arise, and get thee up into the place which the Lord thy God shall choose;

And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and enquire; and they shall shew thee the sentence of judgment:

And that ye may put difference between holy and unholy, and between unclean and clean;

And that ye may teach the children of Israel all the statutes which the Lord hath spoken unto them by the hand of Moses.

For the priest’s lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the Lord of hosts.
