Joshua 8:10

Joshua numbered the people Not all the people, which was needless, and would now have required more time than could have been spared, but that part of the army which he designed to take with him. And this, it seems, he did, that it might be evident the conquest of Ai was effected without any loss of men, and that they might be encouraged hereby to trust in God, and proceed resolutely and boldly in the work of subduing the Canaanites. The elders of Israel Their chief magistrates and rulers under Joshua. These, it is probable, went with Joshua and the army to take care that the cattle and the spoil of the city, which were given by God to all Israel for a prey, might be justly and equally divided between those that went to battle, and the rest of the people.
