Ruth 3:2-6

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.

And it shall be when he lies down, that you shall take notice of the place where he lies, and you shall go and uncover his feet and lie down; then he will tell you what you should do.”

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.
