Ruth 3:6-9

So she went down to the threshing floor and did just as her mother-in-law had told her. When Boaz had eaten and drunk and his heart was happy, he went to lie down at the end of the stack of grain. Then Ruth came secretly, and uncovered his feet and lay down. In the middle of the night the man was startled and he turned over, and found a woman lying at his feet. So he said, “Who are you?” And she answered, “I am Ruth your maid. Spread the hem of your garment over me, for you are a close relative and redeemer.”
