I saw in the visions of my head upon my bed,.... The king goes on to relate what other things presented themselves to his imagination in his dream, concerning this tree which signified himself: and, behold, a watcher: which Saadiah interprets of Bath Kol; but Aben Ezra, Jarchi, Jacchiades, and Ben Melech of an angel; so called because incorporeal, ever watches, and never sleeps, and is always attentive to, and observant of, the commands of God so the angels in the fragment of Enoch are called "egregori", watchers; and the same word is here used in the Alexandrian copy. Some (k) render it "an enemy", "an holy one": according to the sense of the word in Sa1 28:16, and produce it to show that angels are called enemies: and an Holy One; one of the holy angels that never sinned, nor left their first estate, but continued in it; in which they are established by Christ, and are impeccable; are perfectly pure and holy in their nature and actions: such an one came down from heaven; the place of their abode, as it seemed to Nebuchadnezzar in his dream. (k) Lex. Kabalist. in voce p. 54, 55.
