시편 133:2의 Kabbalah

When the beard hair starts to rouse, it seems like a brave hero, a hero victorious in war to exact vengeance against the enemies of Israel (as said in section 150). The sacred ointment flows from the hidden Atika Kadisha, as said, “like the precious ointment upon the head, running down upon the beard, the beard of Aharon” (Tehillim 133:2), referring to the beard of Arich Anpin.
