Joshua 8:10

Numbered the people - ויפקד את העם vaiyiphkod eth haam, he visited the people - inspected their ranks to see whether every thing was in perfect readiness, that in case they should be needed they might be led on to the attack. There is no doubt that Joshua had left the rest of the army so disposed and ready, part of it having probably advanced towards Ai, that he might easily receive reinforcements in case of any disaster to the thirty thousand which had advanced against the city; and this consideration will serve to remove a part of the difficulty which arises from Joshua 8:1, Joshua 8:3, Joshua 8:10, collated with other parts of this chapter. Had he brought all his troops in sight, the people of Ai would not have attempted to risk a battle, and would consequently have kept within their walls, from which it was the object of Joshua to decoy them. See the preceding observations, particularly Joshua 8:10-12 (note).

Numbered the people - Rather, perhaps, "mustered" or "arrayed" them for their march. The distance from the camp at Gilgal to Ai is about fifteen miles. In the evening of the day after the despatch of the 5,000 liers in wait, Joshua and the host might make their appearance in the neighborhood of the city.

8:10 The people - Heb. that people, not all the people of Israel; which was needless, and required more time than could now be spared; but the rest of that host of thirty thousand, whereof five thousand were sent away; the remainder are numbered, to see whether some of them had not withdrawn themselves, taking the advantage of the night, and of the design of laying an ambush; and that it might be evident, this work was done without any loss of men, whereby they might be encouraged to trust in God, and to proceed resolutely in their work. The elders of Israel - The chief magistrates and rulers of Israel under Joshua; and these, I suppose, went with Joshua, and with the army, to take care that the cattle and the spoil of the city, which was given by God to all Israel for a prey, ver.2, 27, might be justly and equally divided between those that went to battle, and the rest of the people.
