Deut 33:2-4

2He said: The Lord came from Sinai, and dawned from Seir upon us; he shone forth from Mount Paran. With him were myriads of holy ones; at his right, a host of his own.3Indeed, O favorite among peoples, all his holy ones were in your charge; they marched at your heels, accepted direction from you.4Moses charged us with the law, as a possession for the assembly of Jacob.
