Ruth 3:3-5

3Wash, put on perfume, and get dressed in your best clothes. Then go down to the threshing floor, but don’t let him know you are there until he has finished eating and drinking.

4When he lies down, note the place where he is lying. Then go and uncover his feet and lie down. He will tell you what to do.” 5“I will do whatever you say,” Ruth answered.
