Ruth 3:9

And he said, who art thou?.... He spoke quick and short, as one displeased, or however surprised and frightened, just coming out of sleep, and in the night:and she answered, I am Ruth thine handmaid; that had gleaned in his fields with his maidens, and with whom he had conversed there, and knew her by name:spread therefore thy skirt over thy handmaid; which seems to account for the reason of her uncovering his feet, or turning up the skirt of his garment that was upon them; not through wantonness and immodesty, but to direct him, when opportunity offered, to spread it over her as a token of his taking her in marriage, and of her being under his care and protection, and of her subjection to him; so the Targum,"let thy name be called upon me to take me for a wife,''Whether the custom now used with the Jews at marriage, for a man to cast the skirt of his "talith", or outward garment, over the head of his spouse, and cover it, was in use so early, is questionable; and yet something like it seems to have been done, as this phrase intimates, and to which there is an allusion in Eze 16:8.
