English: “For she had covered her face” — and because she covered her face he took her for a zonah? R’ Elazar said: [Rather,] that she had covered her face while in her father-in-law’s house.
On the daf / in context: Sotah 10b explains Yehudah did not recognize Tamar because she had been modestly veiled throughout her time in his household.
Type of Learning
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. The phrase is read as background fact, not the immediate cause of the mistake.
What Is Learned
Yehudah failed to recognize Tamar because of her prior modesty in his house, not merely because of the veil at the roadside.
