'Lay' in the Bible
Then he ran to Eli and said, "Here I am, for you called me." But Eli said, "I didn't call you. Go back and lie down." So he went back and lay down.
So Eli said to Samuel, "Go back and lie down. When he calls you, say, "Speak, Lord, for your servant is listening." So Samuel went back and lay down in his place.
So Samuel lay down until morning. Then he opened the doors of the Lord's house. But Samuel was afraid to tell Eli about the vision.
Then the men of Israel and Judah charged forward, shouting a battle cry. They chased the Philistines to the valley and to the very gates of Ekron. The Philistine corpses lay fallen along the Shaaraim road to Gath and Ekron.
He even stripped off his clothes and prophesied before Samuel. He lay there naked all that day and night. (For that reason it is asked, "Is Saul also among the prophets?")
