In the middle of the night, Boaz was startled awake and turned over in surprise to see a woman lying at his feet.

Stay the night, and if he fulfills his duty as your related redeemer in the morning, that will be acceptable. But if he isn't inclined to do so, then, as the LORD lives, I will act as your related redeemer myself. So lie down until morning."
