Verse 10. - This, well-nigh the vilest of all forms of incest, against which the horror naturalis of the heathen, as in the story of Hippolytus, uttered its protest, would seem to have been common among the corruptions of Israel (Amos 2:7; comp. 1 Corinthians 5:1). (For the sin described in the second clause, see notes on Ezekiel 18:6.)

22:1-16 The prophet is to judge the bloody city; the city of bloods. Jerusalem is so called, because of her crimes. The sins which Jerusalem stands charged with, are exceeding sinful. Murder, idolatry, disobedience to parents, oppression and extortion, profanation of the sabbath and holy things, seventh commandment sins, lewdness and adultery. Unmindfulness of God was at the bottom of all this wickedness. Sinners provoke God because they forget him. Jerusalem has filled the measure of her sins. Those who give up themselves to be ruled by their lusts, will justly be given up to be portioned by them. Those who resolve to be their own masters, let them expect no other happiness than their own hands can furnish; and a miserable portion it will prove.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.
