AC 3509 - Isaac, Rebekah, Esau, Jacob

AC 3509 [2-3]
... "Isaac" is the rational mind as to the good
which is of the will,
"Rebekah" being the rational mind with respect to the truth
which is of the understanding;
"Esau" is the good of the natural
that comes forth from the good of the rational;
and "Jacob" is the truth of the natural
that comes forth from the good of the rational through the truth therein.

From these things it may be seen what arcana are contained
in the internal sense of the Word;
but still there are very few which can be described
to human understanding;
while those which transcend it, and cannot be described, are without limit;
for in proportion as the Word penetrates more deeply,
that is, more interiorly, into heaven,
the more innumerable and indescribable the arcana become,
not only to man,
but also to the angels of the lower heaven;
and when it reaches the inmost heaven,
the angels there perceive that the arcana are infinite,
and are altogether incomprehensible to them,
because they are Divine.
Such is the Word.
