Deuteronomy 33:10

8And of Levi he said, Let thy Thummim and thy Urim be with thy holy one, whom thou didst prove at Massah, and with whom thou didst strive at the waters of Meribah;

9Who 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 thy word, and kept thy covenant.

10They shall teach Jacob thy judgments, and Israel thy law: they shall put incense before thee, and whole burnt sacrifice upon thine altar.

11Bless, LORD, his substance, and accept the work of his hands; smite through the loins of them that rise against him, and of them that hate him, that they rise not again.

12And of Benjamin he said, The beloved of the LORD shall dwell in safety by him; and the Lord shall cover him all the day long, and he shall dwell between his shoulders.
