Parashas Vayakhel · Passuk 35:26
Torah Temimah points to classical source on this unit (verified).
English: Rabbi Nechemyah teaches that the women spun the goat hair while it was still attached to the goats.
Derash on “טוו את העזים,” interpreting it as spinning from the goats themselves.
The unusual phrase “they spun the goats” refers to spinning the hair while it remained on the living goats.
