'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 there sat in a window a certain young man named Eutychus, being fallen into a deep sleep: and as Paul was long preaching, he sunk down with sleep, and fell down from the third loft, and was taken up dead.
