Deuteronomy 33:8-10

New Catholic Bible

⁸ Concerning Levi, he said:
Let your Thummim^[a] and your Urim
    be with your holy one
whom you tested at Massah,
    and with whom you contended at the waters of Meribah,
⁹ who said of his father and his mother,
    “I have not seen them,”
nor does he acknowledge his brother
    or even know his own children.
They guarded the words of your covenant and observed it.
¹⁰ He teaches your decrees to Jacob
    and your law to Israel.
He offers incense before your altar
    and whole burnt offerings on it.
