Joshua 1

5-9. There shall not any man be able to stand before thee--Canaan was theirs by a divine grant; and the renewed confirmation of that grant to Joshua when about to lead the people into it, intimated not only a certain but an easy conquest. It is remarkable, however, that his courage and hope of victory were made to depend on his firm and inflexible adherence to the law of God, not only that regarding the extirpation of the Canaanites, but the whole divine code.

10-18. Then Joshua commanded the officers of the people--These were the Shoterim

11-13. command the people, saying, Prepare you victuals--not manna, which, though it still fell, would not keep; but corn, sheep, and articles of food procurable in the conquered countries.
for within three days ye shall pass over this Jordan--that is, the third day, according to Hebrew idiom--the time allotted for getting ready before the encampment in Abel-Shittim broke up and they removed to the desert bank of the river where no victuals were available. At the same time Joshua himself convened the two and a half tribes which had settled east of Jordan, to remind them of their promise ( Numbers 32:1-42 ) to assist their brethren in the conquest of western Canaan. Their readiness to redeem their pledge and the terms in which they answered the appeal of Joshua displayed to great advantage their patriotic and pious feelings at so interesting a crisis.

14. ye shall pass . . . armed--that is, officered or marshalled under five leaders in the old and approved caravan order
all the mighty men of valour--The words are not to be interpreted strictly as meaning the whole, but only the flower or choice of the fighting men.
