Numbers 27:18-21

18The Lord replied to Moses, “Take Joshua son of Nun, a man in whom is such a spirit, and lay your hand on him;

19set him before Eleazar the priest and before the whole community, and commission him publicly.

20Then you must delegate some of your authority to him, so that the whole community of the Israelites will be obedient.

21And he will stand before Eleazar the priest, who will seek counsel for him before the Lord by the decision of the Urim. At his command they will go out, and at his command they will come in, he and all the Israelites with him, the whole community.”
