John Gill Commentary Joshua 10:7

"So Joshua went up from Gilgal, he, and all the people of war with him, and all the mighty men of valor." — Joshua 10:7 (ASV)

So Joshua ascended from Gilgal
Which lay low in the plains of Jericho:

he and all the men of war with him ;
which must not be understood of the whole camp of Israel, which consisted of five hundred thousand fighting men at least; since such a number was unnecessary for this expedition, and could not have proceeded with that haste the case required; nor would it have been prudent and advisable to have left the unarmed people, old men, women, and children, defenceless; but these were a select company of able men, fit for travel as well as war:

and all the mighty men of valour ;
or "even all", as many as were picked out for the purpose, being men of strength, activity, and courage.
