AE 283b - four & six

AE 283b [3]
There were "four cherubim," and "each had six wings,"
because "four" signifies celestial good,
and "six" spiritual good;
for "four" signifies conjunction,
and inmost conjunction with the Lord is through love to Him;
but "six" signifies communication,
and communication with the Lord is by means of charity towards the neighbor.
