Upon this I awaked, etc. Who the speaker is here has been much debated. That Jehovah is meant is not an admissible view. A weak believer may say complainingly, "Why sleepest thou?" but God himself cannot be represented under the image of a sleeper.
There seems, however, to be no reason why the prophet should not have used this language. The doubt is whether a real, physical sleep is meant, or merely an ecstatic condition resembling sleep. Hengstenberg decides for the latter.
But there is no parallel for sleep in the sense of ecstasy, and, on the other hand, there is evidence enough for dreams as the channels of Divine revelation (Genesis 31:10, Genesis 31:11; 1 Kings 3:5; 1 Kings 9:2; Joel 2:28).
As Naegelsbach points out, this is the only unqualifiedly comforting prophecy in the whole book, and may well have left a sweet savour in the prophet's memory. Stern, indeed, was the reality which the moment of his waking brought back to him.
