Ruth 3:7

5And she said unto her, All that thou sayest unto me I will do.

6And she went down unto the 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 corn: 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 thine handmaid: spread therefore thy skirt over thine handmaid; for thou art a near kinsman.
