'Sleep' in the Bible

When he gets ready to go to sleep, take careful notice of the place where he lies down. Then go, uncover his legs, and lie down beside him. He will tell you what you should do."

When Boaz had finished his meal and was feeling satisfied, he lay down to sleep at the far end of the grain heap. Then Ruth crept up quietly, uncovered his legs, and lay down beside him.

Remain here tonight. Then in the morning, if he agrees to marry you, fine, let him do so. But if he does not want to do so, I promise, as surely as the Lord lives, to marry you. Sleep here until morning."
