Plato, again, in the seventh book of the Republic, has called “the day here nocturnal,” as I suppose, on account of “the world-rulers of this darkness;” and the descent of the soul into the body, sleep and death, similarly with Heraclitus. And was not this announced, oracularly, of the Saviour, by the Spirit, saying by David, “I slept, and slumbered; I awoke: for the Lord will sustain me;“ For He not only figuratively calls the resurrection of Christ rising from sleep; but to the descent of the Lord into the flesh he also applies the figurative term sleep. The Saviour Himself enjoins, “Watch;” as much as to say, “Study how to live, and endeavour to separate the soul from the body.”
