'Asleep' in the Bible

Then Jael Heber's wife took a nail of the tent, and took an hammer in her hand, and went softly unto him, and smote the nail into his temples, and fastened it into the ground: for he was fast asleep and weary. So he died.

Then she let him fall asleep on her lap and called a man to shave off the seven braids on his head. In this way, she made him helpless, and his strength left him.
