'Sleep' in the Bible

So the Lord God caused a deep sleep to fall upon the man, and he slept; then He took one of his ribs and closed up the flesh at that place.

Now when the sun was going down, a deep sleep fell upon Abram; and behold, terror and great darkness fell upon him.

Then Jacob awoke from his sleep and said, “Surely the Lord is in this place, and I did not know it.”

Thus I was: by day the heat consumed me and the frost by night, and my sleep fled from my eyes.
