'Sleeping' in the Bible

While he was sleeping from exhaustion, Heber’s wife Jael took a tent peg, grabbed a hammer, and went silently to Sisera. She hammered the peg into his temple and drove it into the ground, and he died.

So while he was sleeping she got the seven twists of his hair worked into her cloth and fixed with the pin, and said to him, The Philistines are on you, Samson. Then awaking from his sleep, he got up quickly, pulling up cloth and machine together.
