Arcana Coelestia # 491
491. The same things are meant by 'sons and daughters' in verses 4, 7, 10, 13, 16, 19, 26, 30, of this chapter, but the character of a Church determines that of its 'sons and daughters', or goods and truths. Here they are truths and goods that men perceived most clearly, for they have regard to the Most Ancient Church, the head and forefather of all other Churches that followed after it.
Genesis 5:4
4
The days of Adam after he became the father of Seth were eight hundred years, and he became the father of sons and daughters.
