And above them, above all the firmaments, are the divine creatures. The feet of the divine creatures correspond in distance to all the firmaments; the ankles of the animals correspond to all of them, the shins of the animals correspond to all of them, the knees of the animals correspond to all of them, the thighs of the animals correspond to all of them, the bodies of the animals correspond to all of them, the necks of the animals correspond to all of them, the heads of the animals correspond to all of them, and the horns of the animals correspond to all of them. Above them is the Throne of Glory: The feet of the Throne of Glory correspond to all of them, the Throne of Glory corresponds to all of them, and the living, almighty, lofty, exalted King dwells above them. And you, Nebuchadnezzar, say: “I will ascend above the heights of the clouds; I will be like the Most High” (Isaiah 14:15), but the next verse states: “Yet you shall be brought down to the netherworld, to the uttermost parts of the pit” (Isaiah 14:15).
