Arcana Coelestia #2848
2848. 'Your seed' means spiritual people who, having that good within them that springs from faith, are saved by the Lord's Divine Human. This is clear from the meaning of 'seed' as faith that is the expression of charity, dealt with in 1025, 1447, 1610, 1941, or what amounts to the same, those members of the human race who possess faith that is the expression of charity, that is, who are spiritual people. They are also called by the Lord 'the seed' and 'the sons of the kingdom', in Matthew,
He who sows the good seed is the Son of Man, but the seed are the sons of the kingdom. Matthew 13:37-38.

1024. That 'with you' means a regenerate spiritual person is clear from what has been stated frequently already; that is to say, 'Noah and his sons' means the spiritual Church which came after the Most Ancient, which was celestial. And because it means the Church, it means each member of the Church, and so a regenerate spiritual person.
