What is written of Moses? (Numbers 20:14-16) "And Moses sent messengers from Kadesh to the king of Edom … And our fathers went down to Egypt … and He hearkened to our voice." He (the king of Edom) said to them (the messengers): You take pride in what your father Isaac bequeathed to you — (Genesis 27:22) "The voice is the voice of Jacob", (Numbers 21:3) "And the L–rd hearkened to the voice of Israel" — and we take pride in what our father Isaac bequeathed to us — (Genesis, Ibid.) "and the hands are the hands of Esav", (Ibid. 40) "and by your sword will you live."
As it is written (Numbers 20:18) "And Edom said to him: Do not pass through me, lest I go out against you with the sword," their trust being only in the sword. But Israel embraced the "trade" (prayer) of their fathers, the trade of Abraham, Isaac, and Jacob.
