And it shall be, when he lieth down,.... On the threshingfloor, under the open air, in order to sleep, and take rest:that thou shall mark the place where he shall lie; the spot he shall lie on, and the direction in which he shall lie, whether east, west, &c.
that when the light shall be taken away, and the darkness of the night come on, she might pretty easily find the place where he lay:and thou shall go in and uncover his feet, and lay thee down; go into the threshingfloor, or to the place where he lay down and gently lay aside the covering upon his feet, whether a blanket, or rug, or his own long clothes, with which his feet were wrapped, and then lay herself down at his feet; this seems to be advised to, in order to give him a hint that there was somebody at his feet.
