TT #24 · Parashas Vayeira · Passuk 18:9
They said to him, “Where is Sarah your wife?” And he said, “Behold, in the tent.”
Torah Temimah points to Yevamos 77a. E-Daf · Sefaria — Yevamos 77a
TT lemma: הנה באהל.
“Behold, in the tent.” From here we learn that the honor of a woman is to dwell within the house.
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. The factual answer “in the tent” is read as a normative statement about a woman’s proper domain.
A woman’s honor is to remain within the house; Sarah’s presence in the tent is the classic illustration.
