Deuteronomy

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 the priests the sons of Levi shall come near; for them the Lord thy God hath chosen to minister unto him, and to bless in the name of the Lord; and by their word shall every controversy and every stroke be tried:

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.

Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall serve him for ever.
