Ruth 3:6-9

6And she went down unto the threshing-floor, and did according to all that her mother-in-law bade her. 7And when Boaz had eaten and drunk, and his heart was merry, he went to lie down at the end of the heap of grain: and she came softly, and uncovered his feet, and laid her down. 8And it came to pass at midnight, that the man was afraid, and turned himself; and, behold, a woman lay at his feet. 9And he said, Who art thou? And she answered, I am Ruth thy handmaid: spread therefore thy skirt over thy handmaid; for thou art a near kinsman.
