{Footnote 2} "Jerusalem" signifies the church in which is
genuine doctrine (n. 402, 3654, 9166). "Gates" signify
introduction to the doctrine of the church, and through
doctrine introduction into the church (n. 2943, 4477, 4478).
"Foundation" signifies the truth on which heaven, the church,
and doctrine are founded (n. 9643).

188. The angels of whom the Lord's celestial kingdom consists dwell
for the most part in elevated places that appear as mountains of
soil; the angels of whom the Lord's spiritual kingdom consists dwell
in less elevated places that appear like hills; while the angels in
the lowest parts of heaven dwell in places that appear like ledges of
stone. These things spring from correspondence, for interior things
correspond to higher things, and exterior things to lower things;{1}
and this is why in the Word "mountains" signify celestial love,
"hills" spiritual love, and "rocks" faith.{2}

{Footnote 1} In the Word what is interior is expressed by what
is higher and what is higher signifies what is interior (n.
2148, 3084, 4599, 5146, 8325). What is "high" signifies what is
internal, and likewise heaven (n. 1735, 2148, 4210, 4599,
8153).

{Footnote 2} In heaven, mountains, hills, rocks, valleys, and
lands are seen exactly the same as in the world (n. 10608). On
the mountains angels who are in the good of love dwell, on the
hills those who are in the good of charity, on the rocks those
who are in the good of faith (n. 10438). Therefore in the Word
"mountains" signify the good of love (n. 795, 4210, 6435, 8327,
8758, 10438, 10608). "Hills" signify the good of charity (n.
6435, 10438). "Rocks" signify the good and truth of faith (n.
8581, 10580). "Stone," of which rock consists, in like manner
signifies the truth of faith (n. 114, 643, 1298, 3720, 6426,
8609, 10376). This is why "mountains" signify heaven (n. 8327,
8805, 9420). And "the summit of a mountain" signifies the
highest part of heaven (n. 9422, 9434, 10608). Also why the
ancients had their holy worship on mountains (n. 796, 2722).

189. There are also angels who do not live associated together, but
apart, house by house. These dwell in the midst of heaven, since they
are the best of angels.

190. The houses in which angels dwell are not erected, as houses in
the world are, but are given to them gratuitously by the Lord, to
everyone in accordance with his reception of good and truth.
