He inquires further, in the book of Aggadah of Rav Yeva Saba, he spoke and explained as follows: the beard begins first with the highest Chesed, as written, “Yours, Hashem, is the greatness and the power and the glory…” (I Divrei Hayamim 1:29). Just as the Sfirot start with Chesed that is called greatness, so does the beard begin with Chesed. Yet here we say it starts with Chochmah and that it follows the path of the three columns – Chochmah, Chesed, Netzach; Binah, Gvurah, Hod; Da’at, Tiferet, Yesod.
Yet the beard includes everything, because the beard starts growing in this manner, as Rav Yeva Saba said. The nine features derive and hang down from the beard and in front of the ears, as said in the Greater Gathering. But they are only constant in another place, that is, in the three columns, as said, as I explained.
