Urim

This was a sacred stone that the High Priest wore on his chest plate. He used it to determine God's will.

It will be at his command that the people will go out and come in

"He will command the community's movements". "Going out" and "coming in" are two opposite commands used to emphasize that he will have full command over their movements.

both he and all the people of Israel with him, the whole community

"both he and the entire nation of Israel"
