To move or remove a neighbor's landmark or boundary stone is to
take away the neighbor's territory. In Mosaic law, which Deuteronomy
parses, and in the law of the other countries that have boundary stones,
this is a crime.                Metaphorically, it is a crime not to allow
others their own cultural territory, or to take it away. Jews believe that
their God has chosen them.  But, in contrast to Christians, Moslems and
other monotheists, Jews do not insist that unbelievers adopt their ways.
There are few missionaries in Judaism -- few movers of boundary stones.   
         Pound's error, as I read the passage from Geoffrey Hill (I haven't
read the poem), is in the metaphorical sense. It has that wonderful
quality, inveterate in Pound, of stating a detail to make the whole idea
blossom out. (The Old Testament writer or writers was/were not bad at that
either.)
        There is also a logical error, in the strict sense of syllogistic 
logic, in any of the infections of human reason like anti-Semitism. Such
errors assume that because a unit in a set has a certain quality, all units
in that set have that quality. I think the Schoolmen called it the excluded
middle. Perhaps Hill also refers to that, because moving a boundary stone 
describes perfectly falling into the abyss of the excluded middle.
