'Sleeping' in the Bible

And He *came and *found them sleeping, and *said to Peter, “Simon, are you asleep? Could you not keep watch for one hour?

And again He came and found them sleeping, for their eyes were very heavy; and they did not know what to answer Him.

And He *came the third time, and *said to them, “Are you still sleeping and resting? It is enough; the hour has come; behold, the Son of Man is being betrayed into the hands of sinners.
