English: The Gemara derives the number of strands from the use of the word “techeiles” here and in the paroches: just as the paroches had six strands, so this garment has six.
On the daf / in context: See the cited source for the full section.
Derash on the verse.
The derashah uses a Gezeirah shavah on “techeiles” to establish the strand count.
