'Sleep' in the Bible

Then Jael Heber's wife took a tent peg, and took a hammer in her hand, and went softly to him, and struck the pin into his temples, and it pierced through into the ground; for he was in a deep sleep; so he swooned and died.

She fastened it with the pin, and said to him, "The Philistines are on you, Samson!" He awakened out of his sleep, and plucked away the pin of the beam, and the web.

She made him sleep on her knees; and she called for a man, and shaved off the seven locks of his head; and she began to afflict him, and his strength went from him.

She said, "The Philistines are upon you, Samson!" He awoke out of his sleep, and said, "I will go out as at other times, and shake myself free." But he didn't know that Yahweh had departed from him.
