(reversion to Devarim 6:4) Jacob prayed to the Holy One Blessed be He and said: From Abraham there came forth Yishmael. From Isaac there came forth Esav — May no "base matter" come forth from me as it did from my fathers! And thus is it written (Bereshith 28:20) "And Jacob vowed a vow, saying, etc." Now would it occur to anyone that Jacob our father would say (Ibid.) "If G-d will be with me … and He will give me bread to eat and a garment to wear (21) and I return in peace to my father's house, and (only then) He will be a G-d to me!" (Obviously,) He will be a G-d to me in any event. How, then, is "and He will be a G-d to me" to be understood? That His name repose upon me, that no "base matter" issue from me from beginning to end.
