Parashas Toldos · Passuk 26:1
There was a famine in the land—aside from the previous famine that had occurred in the days of Avraham—and Yitzchak went to Avimelech, king of the Philistines, in Gerar.
Classical on the second famine (classical source on this passuk; not listed as a numbered Torah Temimah unit here).
Lemma / focus: מלבד הרעב הראשון.
English: Aside from the first famine that was in the days of Avraham—to teach that this was a second famine, and Yitzchak went to Avimelech and did not go down to Egypt until he was commanded.
Derash on the verse (plain sense with classical continuity) — not a formal named middah of the 13: the phrase “aside from the first famine” distinguishes this trial from Avraham’s.
A second famine arose, distinct from Avraham’s; Yitzchak went toward Avimelech in Gerar rather than immediately descending to Egypt.
