'Deep Sleep' in the Bible

And he was in need of food: but while they were getting it ready, a deep sleep came on him;

I was in the town of Joppa, at prayer: and falling into a deep sleep, I saw in a vision a vessel like a great cloth let down from heaven, and it came down to me:

And a certain young man named Eutychus, who was seated in the window, went into a deep sleep; and while Paul went on talking, being overcome by sleep, he had a fall from the third floor, and was taken up dead.
