Numbers 27:21-23

21He is to stand before Eleazar the priest, who will obtain decisions for him by inquiring of the Urim before the Lord. At his command he and the entire community of the Israelites will go out, and at his command they will come in.” 22Moses did as the Lord commanded him. He took Joshua and had him stand before Eleazar the priest and the whole assembly. 23Then he laid his hands on him and commissioned him, as the Lordinstructed through Moses.
