Joshua 8:14

All his people, to wit, all his men of war, for the rest were left in Ai, Joshua 8:16. At a time appointed; at a certain hour agreed upon between the king and people of Ai, and of Beth-el too, who were their confederates in this enterprise, as it may seem from Joshua 8:17. Possibly they might appoint the same hour of the day on which they had fought against Israel with such good success, looking upon it as a lucky hour. Before the plain, i.e. towards or in sight of that plain or valley in which the Israelites were, that so they might put themselves in battle-array. He wist not that there were liers in ambush; the former success having made him more careless and secure, as is usual in such cases; God also blinding his mind, and infatuating him, as he useth to do with those which he intends to destroy.
