Chasidut su Salmi 102:26

David HaMelech already hinted at this when he said, “In ancient days, the earth did You establish, and the work of Your hands are the heavens. They may perish, but You will endure, and all of them will wear out like a garment, like a cloak will You change them and they will pass on.”²¹²Tehillim, 102:26 If every species in the world were a separate entity unto itself, then it would be impossible for anything to change from one form into another, but each one would be like a separate garment for the Godly illumination, and they would only be able to change form by removing the garment and dressing in a different one. The Godly illumination would first dress in the garment of the plant, then remove it and dress in the garment of the animal, and then in the garment of the man.
