In thee have they discovered their father's nakedness
Or, "he discovered" F2, or "uncovered", it being in the singular number; though the Targum, Septuagint, Vulgate Latin, and all the Oriental versions, read in the plural; this, though committed, was done but by a few; it being a sin not so much as named among men, as for a man to lie with his father's wife, ( 1 Corinthians 5:1 ) as Reuben did, ( Genesis 35:22 ) and which is expressly forbidden; and is mentioned first as the capital sin of uncleanness, ( Leviticus 18:6 ) : in thee have they humbled her that was set apart for pollution;
ravished and deflowered such women who had their menstrues; to lie with such was prohibited by the law of God, ( Leviticus 18:19 ) ( 20:18 ) , so that here was a double sin committed; a rape of a woman, whether married or unmarried, at the time of her purgation or sickness; and such a copulation, which at another time would be lawful, ought to be abstained from at such a time, as prejudicial to themselves, and to their posterity, as well as contrary to the divine law.
