'Sleeping' in the Bible

But he was in the stern, sleeping on a cushion. They woke him up and said to him, "Teacher, don't you care that we are about to die?"

Then he came and found them sleeping, and said to Peter, "Simon, are you sleeping? Couldn't you stay awake for one hour?

When he came again he found them sleeping; they could not keep their eyes open. And they did not know what to tell him.

He came a third time and said to them, "Are you still sleeping and resting? Enough of that! The hour has come. Look, the Son of Man is betrayed into the hands of sinners.
