Ruth 3:1-3

And Naomi her mother-in-law said unto her, My daughter, shall I not seek rest for thee, that it may be well with thee? And now is not Boaz our kinsman, with whose maidens thou wast? Behold, he winnoweth barley to-night in the threshing-floor. Wash thyself therefore, and anoint thee, and put thy raiment upon thee, and get thee down to the threshing-floor, but make not thyself known unto the man, until he shall have done eating and drinking.
