"Your terror and your fear": If they are terrified, they are certainly afraid! (i.e., why need "fear" be mentioned?) — "Your terror," on the part of those near you; "and your fear," on the part of those distant. And thus is it written (Joshua 5:1) "And it was, when the kings of the Emori on the side of the Jordan to the west heard, etc." And Rachav, likewise, said (Ibid. 2:10) "For we heard how the L-rd dried up the waters of the Red sea before you … (11) and when we heard, our hearts melted and no spirit remained anymore in any man before you."
And if you would ask: But perhaps the men of Jericho were not great (in stature) and strong — is it not written (Ibid. 2:1) "And Joshua the son of Nun sent out of Shittim two men to spy secretly, saying: Go, spy out the land and Jericho." Now Jericho was part of the land. Why, then, was it singled out for special mention? We hereby infer that they (the men of Jericho) were more formidable than all of them.
