Deuteronomy 33:8-11

8And of Levi he said: “Let Your Thummim and Your Urim be with Your holy one, Whom You tested at Massah, And with whom You contended at the waters of Meribah,

9Who says of his father and mother, ‘I have not seen them’; Nor did he acknowledge his brothers, Or know his own children; For they have observed Your word And kept Your covenant.

10They shall teach Jacob Your judgments, And Israel Your law. They shall put incense before You, And a whole burnt sacrifice on Your altar.

11Bless his substance, Lord, And accept the work of his hands; Strike the loins of those who rise against him, And of those who hate him, that they rise not again.”
