(Devarim, Ibid.) "on the way": at the time of your being tossed about.
"when you came out of Egypt": at the time of your redemption.
"and that he hired against you Bilaam the son of Be'or": (this being the "Because" of Bilaam).
(Devarim, Ibid. 6) "And the L-rd your G-d did not desire to heed Bilaam … and He turned the curse into a blessing for you" — whereby we are taught that the curser is cursed. Why? "For the L-rd your G-d loved you."
(Devarim 23:7) "Do not seek their peace and their good all of your days, forever": Because it is written (Ibid. 20:10) "and you shall call out to it (a besieged city) for peace," I might think that the same should be done with them (Amon and Moav); it is, therefore, written "Do not seek their peace."
