2623. A son. That this signifies the Divine rational is evident from the signification of a “son.” In the internal sense of the Word a “son” signifies truth (n. 489, 491, 533); and as truth is the chief thing in the rational (n. 2072, 2189), the rational is also signified by a “son;” but here the Divine rational, in which principally there is good, which Isaac, who is the “son,” also represents (concerning which hereafter).

8889. 'And the seventh day is a sabbath to Jehovah your God' means when good has been implanted and so the marriage exists. This is clear from the meaning of 'the sabbath' as the heavenly marriage, dealt with above in 8886, thus good which has been implanted through truths and after that given form by them. For good with a person is not spiritual good until it has been given form by truths. And when it has been given form the heavenly marriage exists, since this marriage is good and truth joined together and constitutes heaven itself with a person. All this also goes to explain why 'the seventh day' means a holy state, state being meant by 'day', see 8888, and holy by 'seven', 395, 433, 716, 881, 5265.
