Beshalach: Chapter 12
"She is like the merchant ships"

Rabbi Chiya opens with the verse, "She is like the merchant ships; she brings her food from afar," and "from afar she brings her food." He says that the merchant ships are the Congregation of Yisrael, and that "brings her food" means by a level that dwells on her, that is the central column. He speaks about "all the rivers flow into the sea," telling of the movement and flow through that level, Yesod, down to the sea, Malchut, and from Binah to Yesod, back and forth. Rabbi Yitzchak says that those who merit the World to Come will merit the pairing of supernal Aba and Ima, which never separate.
