Deuteronomy 33:8-11

8Of Levi he said, “Your Thummim and Your Urim belong to Your godly man [Aaron], Whom You tested and proved at Massah, With whom You contended at the waters of Meribah;

9Who said of his father and mother, ‘I did not consider them’; Nor did he acknowledge his brothers, Nor did he regard his own sons, For the priests observed Your word, And kept Your covenant.

10The priests shall teach Your ordinances (judgments) to Jacob, And Your law to Israel. They shall put incense before You, And whole burnt offerings on Your altar.

11O Lord, bless Levi’s substance (ability), And accept and take pleasure in the work of his hands; Crush and shatter the loins of those who rise up against him, And of those who hate him, so that they do not rise again.”
