Ha'azinu: Chapter 19
The hair on the beard of Arich Anpin
Synopsis

Rabbi Shimon says that both the upper and lower beings all look to receive bounty from the Mazal that is the beard of Atika Kadisha, as all life derives from that Mazal; even heaven and earth and bountiful rains come from it. We learn about the thirteen streams of oil, or the thirteen attributes of mercy, that are derived from that beard and that come out to Zeir Anpin.
