Matthew Poole and continuators on Joshua 10:7

7 So Joshua ascended from Gilgal, he, and all the people of war with him, and all the mighty men of valour.

Having, no doubt, asked advice of God first, which is implied by the Answer God gives to him, v. 8.

Or, even, or that is, as this Particle is oft used, hath been noted before. So it seems put here by way of Explication and Restriction; having said all the people of war, he now adds, even all the mighty men, &c. i. e. an Army of the most valiant men picked out from the rest; for it is not probable, either that he would take so many hundred thousands with him, which would have hindred one another; or that he would leave the Camp without an Army to defend it.
