Midrash sur Josué 2:10

(Exodus 18:1) "And Yithro heard": What did he hear that caused him to come (and join Israel)? The war with Amalek, which is juxtaposed with this section. These are the words of R. Yehoshua. He heard of the (prospective) giving of the Torah and he came. For when the Torah was to be given to Israel, all the kings of the earth shook in their palaces, viz. (Psalms 29:9) "and (each king) in his palace accorded glory" (to the L rd). At that time, all the kings of the nations convened with the wicked Bilam and said to him: Is it possible that He is going to do to us as He did to the generation of the flood? He replied: Fools that you are! The Holy One Blessed be He already swore to Noach that he would not bring (another) flood to the world, viz. (Isaiah 54:9) "For this to Me is like the waters of Noach, of which I swore that the waters of Noach would no more pass over the earth." They: Perhaps he will not bring a flood of water, but He will bring a flood of fire? Bilam: He will bring neither a flood of fire nor a flood of water, but the Holy One Blessed be He is giving Torah to His people and to His loved ones, viz. (Psalms, Ibid. 10) "the L rd will give strength ("oz" = Torah) to His people." When all of them heard this from his mouth, they all responded (Ibid.) "May the L rd bless His people with peace," and they turned and went, each to his place. R. Eliezer says: Yithro heard the splitting of the sea and came (to join Israel). For the splitting of the sea was heard from one end of the world to the other, viz. (Joshua 5:1) "And it was, when all the kings of the Emori heard, etc." And thus did Rachav the harlot say to the messengers of Joshua (Ibid. 2:10-11) "For we heard how the L rd dried up the waters of the Red Sea before you when you went out of Egypt … and when we heard, our hearts melted, and no spirit was left in a man before you." They said: Rachav the harlot was ten years old when Israel left Egypt, and all forty years that Israel was in the desert, she plied her trade. At the end of fifty years, she converted, saying: L rd of the universe, I have sinned in three areas: niddah, challah, and candle lighting. Forgive me by virtue of three things: the rope, the window, and the wall, viz. (Ibid. 15) "And she let them down by a rope through the window, for her house was on the side of the wall, and she lived within the wall."...

Similarly, Rahab said: We have heard how the Lord dried up the water of the Red Sea before you, when you came out of Egypt…. As soon as we had heard it, our hearts did melt, and no spirit remained in any man, and it was because of you. This is followed by: For the Lord your God, He is God in heaven above, and on the earth beneath (Josh. 2:10–11). It is also written: And the idols shall utterly pass away (Isa. 2:18), And at that time the Lord alone shall be exalted in that day (ibid., v. 17). Likewise, And saviors shall come up on mount Zion to judge the mount of Esau (Obad 21). And then the kingdom shall be the Lord’s (ibid.), and it is written elsewhere: And the Lord shall be King (Zech. 14:9).

"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.
