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

AD 2017
The custom in Israel was that the master held a great feast on the threshing floor for his boys and for his winnowers, and he slept on the threshing floor, abstaining from the embraces of women that night. The same thing happened at sheep-shearing and after the grape harvest. (Hugh of St. Cher Com Ruth)
