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 And Jehovah said to Joshua, Fear not, neither be dismayed. Take with thee all the people of war, and arise, go up to Ai. See, I have given into thy hand the king of Ai, and his people, and his city, and his land.

2 And thou shalt do to Ai and to its king as thou didst to Jericho and to its king; only, the spoil thereof and the cattle thereof shall ye take as prey for yourselves. Set an ambush against the city behind it.

3 And Joshua arose, and all the people of war, to go up to Ai. And Joshua chose thirty thousand valiant men, and sent them away by night.

4 And he commanded them, saying, See, ye shall be in ambush against the city, behind the city: go not very far from the city, and be all of you ready.

5 And I and all the people that are with me will approach to the city; and it shall come to pass when they come out against us, as at the first, that we will flee before them.
