Numbers 27:21-23

21He 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.”

22So Moses did as the Lord commanded him. He took Joshua and set him before Eleazar the priest and before all the congregation.

23And he laid his hands on him and inaugurated him, just as the Lord commanded by the hand of Moses.
