Ruth 3:5-9

And she said to her, “All that you say I will do.”

So she went down to the threshing floor and did according to all that her mother-in-law had commanded her.

When Boaz had eaten and drunk and his heart was cheerful, he went to lie down at the end of the heap of grain; and she came secretly, and uncovered his feet and lay down.

And it happened in the middle of the night that the man was startled and bent forward; and behold, a woman was lying at his feet.

So he said, “Who are you?” And she answered, “I am Ruth your slave. Now spread your garment over your slave, for you are a redeemer.”
