Joshua 8:12 - Joseph Benson’s Commentary on the Old and New Testaments

He took about five thousand men and set them to lie in ambush Here commentators are divided. The learned Bishop Patrick, with many others, (see Le Clerc and Calmet,) has given it as his opinion, that, besides the thirty thousand whom Joshua had sent off before to lie in ambush, (Joshua 8:3-4,) he now detached five thousand more to guard the roads, and intercept such as might endeavour to save themselves by flight; or to strengthen those that were first sent and that he appeared in arms against the city; with his whole force, according to God's express command, (Joshua 8:1,) to take all the people of war with him. And certainly the letter of the text favours this interpretation. Many, however, think, that all the people were taken only to encamp near the city, and that out of them Joshua chose thirty thousand to be employed in the action, out of which he detached five thousand to lie in ambush, which were as many, they think, as could be supposed to march without being discovered, and then, that with the remaining twenty-five thousand he made the open attack. Or else that the attack was made with the thirty thousand, and that the five thousand formed a separate detachment drawn from the rest of the people. The matter is not perfectly clear, or free from difficulty, either way; and the reader is left to form his own judgment of it from the statement now given.
