Мидраш к Мелахим Б 5:17

(Devarim 11:25) "Your terror and your fear will the L-rd your G-d place on the face of all the land": Why is this mentioned? Because it is written (Ibid. 16:16) "Three times a year shall appear each of your males in the presence of the L-rd your G-d in the place that He chooses," lest Israel say: When we go up to bow down, who will protect our land for us, the Holy One Blessed be He told them: Go up, and I will guard what is yours. As it is written (Shemoth 24:24) "And no man will desire your land when you go up to appear before the L-rd your G-d three times in the year." If it is not desirable in his eyes, why should he come to take his property and his beasts? And, what is more, they are afraid of you, as it is written "Your terror and your fear, etc." And thus do you find with Israel when they do G-d's will. What did Na'aman (the leper of Aram) say to Elisha (II Kings 5:17) "Will there not be given to your servant two mules' burden of earth?" Now does this not follow a fortiori, viz.: If he is afraid to take earth from Eretz Yisrael without permission, how would he come to take his (an Israelite's) property and beasts! This is the intent of "Your terror and your fear will the L-rd your G-d place on the face of all the land where you tread." "as He spoke to you": When did He speak thus? (Shemoth 23:27) "My fear will I send before you, and I shall confound all the people to whom you come."
