Numbers 27:15-21

Then Moses spoke to the LORD, saying: “Let the LORD, the God of the spirits of all flesh, set a man over the congregation, who may go out before them and go in before them, who may lead them out and bring them in, that the congregation of the LORD may not be like sheep which have no shepherd.” And the LORD said to Moses: “Take Joshua the son of Nun with you, a man in whom is the Spirit, and lay your hand on him; set him before Eleazar the priest and before all the congregation, and inaugurate him in their sight. And you shall give some of your authority to him, that all the congregation of the children of Israel may be obedient. He shall stand before Eleazar the priest, who shall inquire before the LORD for him by the judgment of the Urim. At his word they shall go out, and at his word they shall come in, he and all the children of Israel with him—all the congregation.”
