Joshua therefore sent them forth
 The thirty thousand chosen men: 
 and they went to lie in ambush;
 as they were ordered, ( Joshua 8:2 ) : 
 and abode between Bethel and Ai, on the west side of Ai;
 for as Ai was on the east of Bethel, ( Joshua 7:2 ) . Bethel must be on the west of Ai, as Jarchi notes: 
 but Joshua lodged that night among the people;
 the main body of the army, to direct them in the affair of war, how they should behave the next day, when they came to fight; and to inspire them with courage and confidence, that they might not be afraid, because of their having been smitten before by this people, so Ben Gersom; or rather that he and they might be ready in the morning to march towards Ai, as Jarchi and Kimchi.
