Ruth 3:1-3

Then Naomi her mother-in-law said to her, “My daughter, shall I not seek security for you, that it may be well with you? Now is not Boaz our kinsman, with whose maids you were? Behold, he winnows barley at the threshing floor tonight. Wash yourself therefore, and anoint yourself and put on your best clothes, and go down to the threshing floor; but do not make yourself known to the man until he has finished eating and drinking.
