The second part of the dream follows here. Hitherto Nebuchadnezzar has described the beauty and excellency of his state under the figure of a lofty tree which afforded shade to the beasts and on whose fruit they fed, and next as giving, nests to the birds of heaven under its boughs. The cutting down of the tree now follows. I saw, says he, in the visions of my head upon my couch, and, behold, a watcher and a holy one came down from heaven No doubt we ought to understand an angel by a watcher. He is called “ a holy one,” which is only another form of expression for an angel; and they are worthy of this name, because they are perpetually watchful in the performance of God’s commands. They are not subject to slumber, they are not nourished by either food or drink, but live a spiritual life; hence they have no use for sleep, which is the result of drink and food. Lastly, as angels have no bodies, their very spiritual nature makes them watchful. But this phrase not only expresses their nature but also their duty; because God has them at hand to fulfill his bidding, and destines them to the performance of his commands, hence they are called “watchers.” (Psalms 103:20.) In this Psalm angels are said to do his bidding, because, by an agility incomprehensible to us, they run about hither and thither, and fly directly from heaven to earth, from one end of the world to another — from the rising even to the setting sun. Since, therefore, angels can so easily and promptly fulfill God’s orders, they are deservedly called “ watchers ” They are called “ holy ones,” because they are not infected by human infirmities. But we are filled with really sins, not merely because we are earthly, but since we have contracted pollution from our first parents, which vitiates alike the whole body and mind. By this expression, then, Nebuchadnezzar desired to distinguish between angels and mortals. For although God here sanctifies his elect, yet as long as they dwell in the prison of the body they never arrive at the holiness of angels. Here then we mark the difference between angels and men. Nebuchadnezzar could not understand this by himself, but he was taught of God to perceive the destruction of the tree to arise not from man but from the Almighty.
