“Fortunate is the one whose help is the G-d of Yaakov, whose hope is in Hashem his G-d” (Tehillim 146:5). Is it the G-d of Yaakov, and not the G-d of Avraham, and not of Yitzchak? Rather, “the G-d of Yaakov,” because Yaakov did not trust in his father or in his mother when he fled from before his brother and went alone, without money, as you say, “For with [only] my staff I crossed this Yarden” (Bereishis 32:11). And he trusted in HaKadosh Baruch Hu, as it is written, “If G-d will be with me and will guard me, etc.” (Bereishis 28:20). And he asked everything from before HaKadosh Baruch Hu, and He gave it to him.
