Arcana Coelestia #5436
5436. 'All we, the sons of one man are we' means that those truths all have the same origin. This is clear from the meaning of 'the sons', who in this case are the sons of Jacob, as truths in general, often dealt with already. As regards 'of one man' meaning that they all have the same origin, this is evident without explanation.
Sorrow
The woman condemned to 'bring forth sons in sorrow' denotes the anxieties and combats in the production of truths.
