Numbers 27:21-23

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.”

22So Moses did as the Lord commanded him; he took Joshua and set him before Eleazar the priest and before the whole community.

23He laid his hands on him and commissioned him, just as the Lord commanded, by the authority of Moses.
