Deuteronomy 33:8-10

The Voice

Moses: Your Thummim and Urim belong to your loyal servant,
        the man you tested at Massah and had a dispute with at Meribah about the water.
⁹     When the Levites carry out the law,
        they don’t give special treatment to their fathers or mothers
    Or favor their relatives or recognize their children.
        They obey Your word and keep Your covenant.
¹⁰     They teach Jacob Your rules;
        they teach Israel Your law.
    They set incense before You
        and offer burnt sacrifices on Your altar.
