6418. 'The son of a fertile one beside a spring' means the fruitfulness of truth from the Word. This is clear from the meaning of 'the son' as truth, dealt with in 489, 491, 533, 2623, 2803, 2813, 3773, 3704; from the meaning of 'a fertile one' as the fruitfulness of truth, for fertility, like bearing and birth, applies in the spiritual sense to truth and good, 1145, 1255, 3860, 3868, 4070, 4668, 5598; and from the meaning of 'a spring' as the Word, dealt with in 2702, 3424, 4861. From this it is evident that 'the son of a fertile one beside a spring' means the fruitfulness of truth from the Word. Those who belong to the Lord's spiritual Church, the Church represented here by 'Joseph', come to know what good is from truth received from the Word, and so are introduced into good by means of truth. Then follows the fruitfulness meant by 'a fertile one'.

1145. 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.
