‘So Joshua rose up early in the morning, and brought Israel near by their tribes, and the tribe of Judah was selected.'
Joshua always rose early on special occasions. Perhaps it was in order to pray before acting. Or perhaps he was concerned to obey YHWH as quickly as possible. (How good it would be if we also were so eager to do God's will). And he brought Israel near, by their tribes. Perhaps he had twelve sticks with their tribal names on and these were tossed in some way by the priest. Perhaps he went through them one by one saying ‘Is this the one?' with the priest tossing the Urim and Thummim to see if it gave a ‘yes' reply. The method of selection bit by bit demonstrates that it was not a direct word from God to Joshua. But whichever way it was the lot fell correctly and Judah was selected.
