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 saith unto Joshua, `Fear not, nor be affrighted, take with thee all the people of war, and rise, 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 hast done to Ai and to her king as thou hast done to Jericho and to her king; only, its spoil and its cattle ye spoil for yourselves; set for thee an ambush for the city at its rear.'
3 And Joshua riseth, and all the people of war, to go up to Ai, and Joshua chooseth thirty thousand men, mighty ones of valour, and sendeth them away by night,
4 and commandeth them, saying, `See, ye are liers in wait against the city, at the rear of the city, ye go not very far off from the city, and all of you have been prepared,
5 and I and all the people who [are] with me draw near unto the city, and it hath come to pass when they come out to meet us as at the first, and we have fled before them,
