3 Reside in this land, and I will be with you and bless you; I will assign all these lands to you and to your heirs, fulfilling the oath that I swore to your father Avraham.

26:3 Reside in this land, and I will be with you and bless you
Yitzchak is warned that despite the famine in Eretz Yisrael, he is not to escape the hardship by fleeing to Egypt. Though Avraham went down to Egypt when there was a plague in Israel, and Yaakov likewise descended to Egypt towards the end of his life, God told Yitzchak not to leave the Land of Israel. Due to the unique spiritual status he acquired after being offered on the altar, Yitzchak was the only one of the three forefathers to never step foot outside of the Holy Land.
