Ruth 3:4

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.

Ver. 4. And it shall be, when he lieth down.] He lay on the floor, as best liked himself, without bed or pallet. Hollinshead saith, that some old men he knew who told of times in England, that if the good man of the house had a mattress, or flock-bed, and a sack of chaff to rest his head on, he thought himself as well lodged as the lord of the town: for ordinarily they lay upon straw pallets covered with canvas, and a round log under their heads instead of a bolster.
