2623. 'A son' means the Divine Rational. This is clear from the meaning of 'a son'. In the internal sense of the Word 'a son' means truth, 489, 491, 533; and because truth is the principal element in the rational, 2072, 2189, 'a son' also means the rational. But here the Divine Rational is meant in which the principal element is good. 'Isaac' too, to whom 'a son' refers, represents this good, as will be shown further on.
