Rabbi Chiya opens with: "All the rivers run into the sea, yet the sea is not full...," saying that these rivers are the secret of the Sfirot that are the holy rivers that filled the great sea, Malchut. The sea then flows over and provides water for the animals in the field. The sea of Malchut takes in the springs, the lights of Zeir Anpin, and pours them out into the Holy Chariots below. All of these are named and counted by Malchut. We are told that 'the Tabernacle' in the opening verse is Malchut, and that the grades that she waters correspond to the utensils of the tabernacle, all of which are called by name.
