'Sleeping' in the Bible

They got up early [the next day]; and at dawn Samuel called Saul [who was sleeping] on the roof, saying, “Get up, so that I may send you on your way.” Saul got up, and both he and Samuel went outside.

So David and Abishai went to the army during the night, and there was Saul lying asleep inside the circle of the camp with his spear stuck in the ground by his head; and Abner and the people were lying around him.
