Reply To: Payos behind the ears? Why?

The hair on head is called sayor, same letters as word “shiyur” (measure) which is a limitation, known as gevurah. Likewise, it has the same letters as “se’or” yeast, which is known to be associated with Din (judgement). (It is also the same letters as “sha’ar” (gate) but that is another discussion, and also the word se’ora – barley, as in sefirat haOmer when the 24,000 students of R’ Akiva died).
