Kabbalah su II Samuele 6:19

Firmament is mentioned five times on the second day, and the life of the worlds, which is Yesod of Zeir Anpin, passes through them and guides the worlds through them. They all are comprised of each other. Had the Central Column not settled the dispute, neither would have included the other nor be harmonized. These five firmaments are equivalent to the 500 years to which the Tree of Life, which is Zeir Anpin, is attached to produce offspring and fruits in the world. All the waters of Creation, namely the kinds of Mochin that flow out from Beresheet, which is Arich Anpin, are divided under it and through it into the upper waters and the lower waters. King David, who is the secret of the Female principle, receives everything from Zeir Anpin. He then distributes it down to the lower worlds of Briyah, Yetzirah and Asiyah, as it is written: "And he distributed among all the people, among the whole multitude" (II Samuel 6:19). It is also written: "You give it to them; they gather it" (Psalms 104:28) and "She rises also while it is yet night, and gives food" (Proverbs 31:15).
