Deuteronomy 33:8-11 - Blessing On Levi

⁸ And of Levi he said, Let your Thummim and your Urim be with your holy one, whom you did test at Massah, and with whom you did strive at the waters of Meribah; ⁹ Who said unto his father and to his mother, I have not seen him; neither did he acknowledge his brethren, nor knew his own children: for they have observed your word, and kept your covenant. ¹⁰ They shall teach Jacob your judgments, and Israel your law: they shall put incense before you, and whole burnt sacrifice upon your altar. ¹¹ Bless, LORD, his substance, and accept the work of his hands: strike the loins of them that rise against him, and of them that hate him, that they rise not again.
