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.

And when Boaz had eaten and drunk, and his heart was merry, he went to lie down at the end of the heap of corn: and she came softly, and uncovered his feet, and laid her down.

And it came to pass at midnight, that the man was afraid, and turned himself: and, behold, a woman lay at his feet.

And she lay at his feet until the morning: and she rose up before one could know another. And he said, Let it not be known that a woman came into the floor.
