Malachi 2:7

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

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 inquire; and they shall show thee the sentence of judgment: And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall show thee; and thou shalt observe to do according to all that they inform thee: According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall show thee, to the right hand, nor to the left.

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:

Take heed in the plague of leprosy, that thou observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so ye shall observe to do.

And with them he sent Levites, even Shemaiah, and Nethaniah, and Zebadiah, and Asahel, and Shemiramoth, and Jehonathan, and Adonijah, and Tobijah, and Tobadonijah, Levites; and with them Elishama and Jehoram, priests.

And Hezekiah spake comfortably unto all the Levites that taught the good knowledge of the LORD: and they did eat throughout the feast seven days, offering peace offerings, and making confession to the LORD God of their fathers.

For Ezra had prepared his heart to seek the law of the LORD, and to do it, and to teach in Israel statutes and judgments.
