'Feet' in the Bible

And it shall be, when he lies down, that thou shalt mark the place where he shall have lain down, and thou shalt go in, and uncover his feet, and lay thyself down; and he will shew thee what thou shalt do.

And Boaz ate and drank, and his heart was merry, and he went to lie down at the end of the heap of corn. Then she went softly, and uncovered his feet, and laid herself down.

And it came to pass at midnight, that the man was startled, 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 threshing-floor.
