Leviticus 20:20 Meaning and Commentary

Leviticus 20:20

And if a man shall lie with his uncle's wife
His uncle being dead, and he marry her, which is forbidden, ( Leviticus 18:14 ) ; he hath uncovered his uncle's nakedness:
his wife's, which was his, and therefore the kindred too near for a man to marry in, and such a copulation must be incestuous: they shall bear their sin;
"both" of them, as the Vulgate Latin, as before, ( Leviticus 20:19 ) ; the punishment of it, as follows: they shall be childless;
which Jarchi and other Jewish writers interpret, if they had any children at this time, that is, by a former marriage, they should die and be buried before them, which was reckoned a great punishment, see ( Jeremiah 22:30 ) .
