juncture of time? Why did Yaakov designate Hashem as being the “G-d
of Yitzchak” as opposed to the “G-d of Avraham”?
Just as Yitzchak did not descend to Egypt, Yaakov did not want to, either.
Avraham Avinu was forced to leave Canaan. Pharaoh even gave Avraham
and Sarah the land of Goshen as a present. This is why Yaakov did not
want to invoke the merit of Avraham in his plea.
When Yosef was abducted, Yitzchak shared in the pain and suffering of
Yaakov, shedding tears and offering prayers on his behalf. As a sign of
his gratefulness, Yaakov’s sacrifices to Hashem contained a reference to
Yitzchak.

“G-d spoke to Yisrael in night visions and He
said, ‘Yaakov, Yaakov.’ And he said, ‘Here I
am’”

(Bereishit 46:2)
