What did Hashem mean when He said to Yitzchak that, "Ve'hisbar?chu be?Zar?acha Kol Goyei ha?Aretz"?
Rashi: He meant that people will say to their own children, 'May (you or 1 ) your offspring be like the offspring of Yitzchak!' 2
Targum Onkelos and Targum Yonasan: He meant that all the nations of the land will be blessed because of Yisrael - that Yisrael will be the conduit through which B?rachah will extend to the whole world). 3
Rashi (in an earlier version).
The source for this is Ya?akov, who said to Yosef, "B?cha Yevarech Yisrael leimor Yesimcha Elokim ke?Efrayim ve?chi?Menasheh" (48:20).
See Rashi in Devarim 11:12, who presents a similar idea.
QUESTIONS ON RASHI
Rashi writes: "'They shall bless themselves (v'Hisbarechu)' - A person would say to his son, 'may your children be like Yitzchak's.'" Why doesn't Rashi explain that all the nations would receive a blessing in Yitzchak's merit?
Gur Aryeh: The word "v'Hisbarechu" is in the reflexive, indicating something one does to oneself. Rashi therefore explains that a person would bless his own family.
