Ruth 3:5

Then Naomi her mother in law said unto her, My daughter, shall I not seek rest for thee, that it may be well

And now is not Boaz of our kindred, with whose maidens thou wast? Behold, he winnoweth barley to night in the threshingfloor.

Wash thyself therefore, and anoint thee, and put thy raiment upon thee, and get thee down to the floor: but make not thyself known unto the man, until he shall have done eating and drinking.

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