Angelic Quotes

I am currently in a dialog with a friend of mine, and I
do not have the resources to answer the following:

                                Psalms 2:9
     Thou shalt break them with a rod of iron; thou
     shalt dash them in pieces like a potter's vessel.

                             Revelation 2:27
     And he shall rule them with a rod of iron; as the
     vessels of a potter shall they be broken to

The LXX corrupted the text from "break" to "rule" and when
the angel quoted it to John he did so ver batim from the
LXX.  The DSS demonstrate without question that "rule" is an
error.  As I said before, if an angel from heaven can quote
existing erroneous readings, why can't Joseph Smith?
