Ruth 3:1-3

Then her mother-in-law Naomi said to her, “My daughter, shall I not seek security for you, that it may go well for you?

Now then, is Boaz not our relative, with whose young women you were? Behold, he is winnowing 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 reveal yourself to the man until he has finished eating and drinking.
