He shall stand before Eleazar the priest, who will inquire for him by the judgment of the Urim before Yahweh. At his word they shall go out, and at his word they shall come in, he and all the Israelites with him, the whole congregation.”
In context
19Set him before Eleazar the priest and before the whole congregation, and commission him in their sight. 20Give him some of your authority, so that the whole congregation of the Israelites will obey him. 21He shall stand before Eleazar the priest, who will inquire for him by the judgment of the Urim before Yahweh. At his word they shall go out, and at his word they shall come in, he and all the Israelites with him, the whole congregation.” 22So Moses did just as Yahweh had commanded him. He took Joshua and set him before Eleazar the priest and before the whole congregation. 23He laid his hands on him and commissioned him, just as Yahweh had spoken through Moses.
