Ruth's Nighttime Encounter with Boaz on the Threshing Floor.

Then Naomi her mother in law said to her, My daughter, shall I not seek rest for you, that it may be well with you?

And now is not Boaz of our kindred, with whose maidens you were? Behold, he winnows barley to night in the threshing floor.

Wash yourself therefore, and anoint you, and put your raiment on you, and get you down to the floor: but make not yourself known to the man, until he shall have done eating and drinking.

And it shall be, when he lies down, that you shall mark the place where he shall lie, and you shall go in, and uncover his feet, and lay you down; and he will tell you what you shall do.
