Deuteronomy 33:8-10

NHEB(i) 8 Of Levi he said, "Give to Levi your Thummim and your Urim to your faithful one, whom you proved at Massah, with whom you strove at the waters of Meribah; 9 who said of his father, and of his mother, 'I have not seen him;' Neither did he acknowledge his brothers, Nor did he know his own children: For they have observed your word, and keep your covenant. 10 They shall teach Jacob your ordinances, and Israel your law. They shall put incense before you, and whole burnt offering on your altar.
