Origen, in On First Principles 4.1.22 understood "Jerusalem" to refer, not simply to the city, but the adjacent territory thereof:
Whatever, then, is either narrated
or predicted of Jerusalem, must, if we accept the words of Paul as those of
Christ speaking in him, be understood as spoken in conformity with his opinion
regarding that city which he calls the heavenly Jerusalem, and all those places
or cities which are said to be cities of the holy land, of which Jerusalem is
the metropolis. (ANF 4:371)
