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 be afraid or discouraged. Take the whole army with you, and go up and attack Ai. See, I have delivered into your hand the king of Ai, his people, his city, and his land.

2 And you shall do to Ai and its king as you did to Jericho and its king, except that you may carry off their plunder and livestock for yourselves. Set up an ambush behind the city.”

3 So Joshua and the whole army set out to attack Ai. Joshua chose 30,000 mighty men of valor and sent them out at night

4 with these orders: “Pay attention. You are to lie in ambush behind the city, not too far from it. All of you must be ready.

5 Then I and all the troops with me will advance on the city. When they come out against us as they did the first time, we will flee from them.
