Verse Nu21-27b Nu21-27c discussing Joshua's seeking advice from Elazar using Urim and Tumim states And he shall stand before Eleazar the priest, who shall ask for him according to the judgment of Urim before the Lord; at his word shall they go out, and at his word they shall come in, both he, and all the people of Israel with him, all the congregation Rashi notes that the underlined words, ask for him ... urim references verses 1S30-07:08 and Ex28-06:30 discussing an inquiry by David thru the Urim whether a military maneuver will be successful Hence the Rashi comment Joshua shall ask [from the Urim by Elazar] when Joshua wishes to go to war

Rashi comments: Joshua shall ask [from the Urim by Elazar] when Joshua wishes to go to war

Advanced Rashi: Note that we could have equally brought other verses for reference: For example, Ju20-27:28 also gives an example of inquiry thru the Urim about the propriety of a military action.

Also note that this refernce example is complex in that the reference is sequential:
• Nu21-27 speaks about asking from the Urim
• Ex28-06:30 explains how the urim are on the breastplate and
• The breastplate is connected by a cord to the
• Ephod garment
• And that is exactly what David inquires from in 1S30-07:08 from the Ephod.

Finally I note the oddity that many history, military and political books seem to have overlooked the importance of organized religion in general and the priests in particular in determining and even allowing military action. There are many examples. We find in the Talmud / Midrash for example that a priest stopped Alexander the Great from attacking. Similarly the holiday of Chanukah is a holiday about Priestly military activities. The Bible relates that a prophet stopped a civil war when the monarchy split in two after Solomon's death. Military records show that many generals, even those from non religious nations, have sought religious confirmation of their planned activities.
