What's in a chulya?
He describes the knot of the hand Tefilin as having three חוליות on one side and 3 (or 4) on the other side.
The head Tefilin has "two that are four" חוליות, two on the top knot and two on the bottom of the knot.
מִי כְּהֶחָכָם וּמִי יוֹדֵעַ פֵּשֶׁר דָּבָר?
It seems to me that this has to do with the number of "loops" used when tying these knots. I would be grateful in anyone can shed some light on to this description what is meant by חוליות here.
