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 (see on De 17:18) 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.
