Joshua 8:3

We have here an account of the taking of Ai by stratagem. The stratagem here used, we are sure, was lawful and good; God himself appointed it, and we have no reason to think but that the like is lawful and good in other wars.

Now in the account here given of this matter, I. There is some difficulty in adjusting the numbers that were employed to effect it. Mention is made (Jos 8:3) of 30,000 that were chosen and sent away by night, to whom the charge was given to surpris…

8:3 set out to attack Ai: This first sentence provides a summary; details are filled in over the next several paragraphs. • The Hebrew words translated 30,000 might mean 30 units (see study note on Exod 12:37) or 30 chieftains. As the battle developed, this group would wait in ambush until Joshua called them out (Josh 8:18-19).
