In thee have they discovered their father's nakedness,.... Or, "he discovered" b, 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, 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.
