In what way is the Kohen Gadol superior to his fellow Kohanim?
Ba'al ha'Turim: As hinted in the 'Hey' of ha'Gadol.
Moshav Zekenim: If he is not the richest, they make him the richest - the letters of ha'Gadol spell Gadlehu. He must be greater than them, for he is greater even than Micha'el, the great minister - "v'Chol Adam Lo Yihyeh b'Ohel Mo'ed b'Vo'o" (16:17), even angels about whom it says "u'Dmus Pneihem Pnei Adam" (Yechezkel 1:10).
What is the meaning of "Lo Yifra?
Rashi: A growth of thirty days. Moshav Zekenim - Mo'ed Katan (24a) expounds that a different Avel who does not grow his hair long or tear his clothes will be Chayav Misah. (We know that an Avel is forbidden to cut his hair for 30 days. Really, the Gemara learned from 10:6, but also there, even Aharon's sons had the law of a Kohen Gadol - refer to 10:6:1:2, 10:6:1:2 2
