Arcana Coelestia #2019
2019. 'And your seed after you' means conjunction with those who have faith in Him. This is clear from the meaning of 'seed' as faith, dealt with in 1025, 1447, 1610, and also from the meaning of 'after you' as following. In the Word 'walking after someone' is a frequently used phrase, as in Jeremiah 7:6; 8:2; Ezekiel 20:16; also Mark 8:34; Luke 9:23; 14:27. Here therefore 'your seed after you' means those who have faith and who follow Him. In the internal sense they are those born from Him.

That 'these are the generations of the sons of Noah' means derivative matters of doctrine and derivative forms of worship in the Ancient Church, which in general is Noah, is clear from the meaning of 'generations', dealt with already. In the external or literal sense, generations involve one being begotten from another, as is well known; but in the internal sense everything has regard to things that are celestial and spiritual, that is, to what are matters of charity and of faith. Thus 'generations' here means things of the Church, and therefore matters of doctrine, as will be better evident from what follows.
