Joshua 8:3 Meaning and Commentary

Joshua 8:3

So Joshua arose, and all the people of war, to go up against
Ai
As the Lord had commanded him:

and Joshua chose out thirty thousand mighty men of valour;
out of all the men of war; these were a select company, picked men, not the whole army, as some have thought, for he was ordered to take all the people of war, as he did:

and sent them away by night;
from the main army, that they might pass the city and get behind it undiscovered, for they were sent for an ambush; and of these some were to take the city, and be left in it to burn it, and some to smite the men of Ai, as Abarbinel notes.

Joshua 8:3 In-Context

1 Then the Lord said to Joshua, "Do not fear or be dismayed; take all the fighting men with you, and go up now to Ai. See, I have handed over to you the king of Ai with his people, his city, and his land.

2 You shall do to Ai and its king as you did to Jericho and its king; only its spoil and its livestock you may take as booty for yourselves. Set an ambush against the city, behind it."

3 So Joshua and all the fighting men set out to go up against Ai. Joshua chose thirty thousand warriors and sent them out by night

4 with the command, "You shall lie in ambush against the city, behind it; do not go very far from the city, but all of you stay alert.

5 I and all the people who are with me will approach the city. When they come out against us, as before, we shall flee from them.
