Deuteronomy 33
8 Ref And of Levi he said, Give your Thummim to Levi and let the Urim be with your loved one, whom you put to the test at Massah, with whom you were angry at the waters of Meribah;
9 Ref Who said of his father, Who is he? and of his mother, I have not seen her; he kept himself separate from his brothers and had no knowledge of his children: for they have given ear to your word and kept your agreement.
10 Ref They will be the teachers of your decisions to Jacob and of your law to Israel: the burning of perfumes before you will be their right, and the ordering of burned offerings on your altar.
