and it cometh to pass when he lieth down, that thou hast known the place where he lieth down, and hast gone in, and uncovered his feet, and lain down, -- and he doth declare to thee that which thou dost do.'

And Boaz eateth and drinketh, and his heart is glad; and he goeth in to lie down at the end of the heap; and she cometh in gently, and uncovereth his feet, and lieth down.

And it cometh to pass, at the middle of the night, that the man trembleth, and turneth himself, and lo, a woman is lying at his feet.

And she lieth down at his feet till the morning, and riseth before one doth discern another; and he saith, 'Let it not be known that the woman hath come into the floor.'
